In the following pages an account of the genus Viburnum in Malaysia is presented. 2. The distribution of its species is briefly discussed and a map relating to it added. 3. The main part of the present paper consists of keys to the sections and species, followed by a systematic treatment of the 16 species admitted for the region. 4. Three new subsections are proposed, viz. Viburnum subsect. Punctata Kern, subsect. Sambucina Kern, and subsect. Lutescentia Kern. Viburnum subseries Coriacea Maxim, is reduced to the rank of a subsection. 5. Three species and two varieties are described as new, viz. Viburnum ampli- ficatum Kern, V. clemensae Kern, V. hispidulum Kern, V. coriaceum, var. longiflorutn Kern, and V. sambucinum var. subglabrum Kern. 6. The following species are reduced to the rank of varieties: Viburnum flori- bundum Merr. has become V. luzonicum var. floribundum (Merr.) Kern, and V. sinu- atum Merr. has become V. luzonicum var. sinuatum (Merr.) Kern. 7. The following reductions'to synonymy are made: Viburnum longistamineum Ridl. to V. sambucinum- var. subglabrum Kern; V. sumatranum Miq., V.villosum Ridl., and V. inopinatum Craib all to V. sambucinum var. tovientosum Hallier f.; V. forbesii Fawc. partly to V. sambucimim Bl., partly to V. coriaceum BL; and V. zippelii Miq. to V. japonicum (Thunb.) Spr. 8. Emended descriptions of Viburnum beccarii Gamble and of V. junghuhnii Miq. are given.

With Mount Kinabalu as a centre, Borneo possesses a number of endemics, of which up to the present four are known: V. amplificatum, V. clemen- sae, V. hispidulum, and V. vernicosum. V. sambucinum inhabits the largest area, spreading over the Malay Peninsula and almost the whole of the Malay Archipelago, inclusive of the Lesser Sunda Islands and the Mo- luccas. The area of V. lutescens is nearly equal, reaching as far as Borneo and the western Lesser Sunda Islands Bali and Lombok. That of V. coria- ceum is more restricted; in Malaysia this species occurs only in Sumatra, Java, and the Lesser Sunda Islands. V. punctatum, practically confined to the Asiatic continent, possesses an exclave in North Sumatra. V. beccarii 1. The distribution of the Malaysian species of Viburnum. The numbers are those of the species in this paper. only known from the Malay Peninsula and the northern half of Suma- tra ; V. junghuhnii from a few localities in Sumatra and Java. None of these species reaches the Philippines. 110 R E I N W A R D T I A [VOL. 1 The northern group inhabits the Philippines. The three species of the 'glaberrimum'-group (V. glaberrimum, V. platyphyllum, and V. cornu- tidens) are apparently endemics. Of the other Philippine species of Viburnum, which also occur in China, Formosa, etc., V. odoratissimum reaches Celebes, and V. luzonicum, Buru. It is only in these two islands that the southern and the northern group overlap somewhat. V. propin- quum has penetrated from the Asiatic continent only as far as Luzon. About the polymorphy of the genus only a few remarks will be made. The widely distributed species show an astonishing plasticity. All the numerous attempts to divide these agglomerates into smaller units I consider as failures. In my opinion the way out of the difficulties will not be found merely by morphological researches. The polymorphy even goes so far, that the usually widely differing V. sambucinum and V. coria- ceum show a surprising similarity at the boundary of their area in the Lesser Sunda Islands, which at the same time is the boundary of the area of the genus. Especially the shape of the corolla proves to be of comparatively small taxonomical value. The tubular corolla of V. coria- ceum, in Sumatra often 6 mm long, has here become short; the campanul- ate corolla of V. sambucinum on the other hand has become slightly tubul- ar by lengthening of the tube which is here even distinctly longer than the lobes. The filaments of the Malaysian species are usually described as in- serted at the base of the corolla. As to V. odoratissimum and V. coriaceum. this is certainly incorrect, while also in V. junghuhnii the lower part of the filaments is adnate to the corolla. Since Oersted's work on the genus much importance has correctly been attached to the shape of the endocarp. Its taxonomical value should indeed not be underestimated, although the number of the grooves cannot always easily be decided. Except with V. propinquum, the endocarp is always dorsiventrally compressed in the Malaysian species. Besides, it is either undulate (two dorsal, one or three ventral grooves) or inflexed. In the inflexed endocarp the ventral side becomes internal. The endocarp of V. junghuhnii and V. amplificatum is both undulate and inflexed and so shows a two-lobed intrusion. Up till now too little attention has been paid to the presence or absence of pitted glands at the leaves, especially of the deep pits at the base of the blade. With V. beccarii and V. vernicosum the presence of the glands is very characteristic. Thus, V. hispidulum can always be distin- guished from V. vernicosum by the absence of glandular pits. The margin- 1951] KERN: Viburnum in Malaysia 111 al glands in V. propinquum, mentioned nowhere, I have not met with in any other species of Viburnum. As an elaboration of the whole genus is still wanting, the subdivision of the genus is as yet insufficient. Particularly the section Thyrsosma is rather heterogeneous and further division would be highly desirable. The scheme of the Malaysian sections given below corresponds mainly to that of Render.

Inflores- cence umbellate, corymbiform, 3—4 times compound, up to 10 cm across; axes thinly stellate-pubescent; peduncle short, up to 2.5 cm long; primary rays 5—7, light green; bracteoles small, ovate, soon caducous; flowers somewhat scented. Calyx-limb obscurely toothed, 1.5—2 mm in diameter; teeth triangular, acute. Corolla tubular, ellipsoid-obovoid in bud, creamy white to white, sometimes pink, usually dotted with brown on the outside; tube usually 3—4 mm long (see var. longiflorum) ; lobes erect, rounded triangular, 1 mm. Stamens exserted; filaments ligulate, subulately tapering . towards the top, in the flower-bud with inflexed apical part, white, adnate to the tube of the corolla 0.5—1 mm above the base, 4—6(—7) mm long; anthers oblong, purplish, 1—1.5 mm long. Ovary cylindrical, glabrous or lepidote, 1.5—2 mm long; style glabrous, white, short, 0.5—1 mm. Drupe ovoid to broad-ellipsoid or even nearly spherical, in vivo only slightly dorsiventrally compressed, bluish black, 6—6.5 mm long, 5—6 mm wide; endocarp undulate in cross-section, 2-grooved on the dorsal side, 3-grooved on the ventral side, the lateral grooves, however, often obsolete. ECOLOGY. — In open primary and secondary forests, especially at their outskirts, sometimes in brushwood or in grassy plains. Only in the higher mountain region, from 1000 (especially 1500) m upward, there often common and one of the pioneers in the natural re-afforestation. Flowering and fruiting throughout the year. USES. — Not recorded. DISTRIBUTION. — SE Asia; in Malaysia only in the Greater Sunda Islands Sumatra and Java, and in the Lesser Sunda Islands (Bali, Lom- 1951] KERN: Viburnum in Malaysia 117 bok, Flores, Timor). Not occurring in the Malay Peninsula and in the Philippines. Viburnum coriaceum var. longiflorum Kern, var. nov. Corollae tubus circiter 6 mm longus, lobi 1 mm longi; filamenta usque ad 6 mm longa, 2—3 mm supra basin corollae adnata. Tube of the corolla about 6 mm long, lobes 1 mm; filaments up to 6 mm long, adnate to the corolla 2—3 mm above the base. DISTRIBUTION. — Sumatra, East Coast Residency. TYPE. — Yates 1567 (A). Viburnum coriaceum is extremely variable in all its parts, mainly as to the shape of the leaves. Usually these are slenderly acuminate and remotely dentate, but the acumen may also be short or nearly wanting, the margins serrate or nearly entire. The flowers, too, vary in colour and size. In revising the Malaysian species of Viburnum in the Herbarium of the Arnold Arboretum I was struck by the large flowers and the very shining, vernicose leaves of the specimens Yates 1567 and Hamel & Rahmat Si Torus 639, both from North Sumatra. At first I believed they might represent a distinct species. However, neither in the leaf-shape nor in the fruits could I find valid differences. For this reason it seems pref- erable to regard the large-flowered specimens as a variety, the more so. as Burkill 16312 and Yates 105 with a corolla of 6 mm length may be regarded as intermediate. The small-flowered form also occurs in North Sumatra. However remarkable the viscosity of the leaves may be, it should be remembered that the normal Javanese V. coriaceum may also be viscid, as is evident from an annotation on the label of Clason K198 from Mount Kelud. On account of the strikingly shining leaves I presume nevertheless, that the fruiting specimens Yates 976, Bangham 928 & 948, and Hamel 443 may belong to the large-flowered form. Noteworthy also are the specimens collected in the Lesser Sunda [Islands during the Elbert Expedition of 1909—1910 and the Rensch Ex- pedition of 1927. They greatly resemble the aberrant V. sambucinum of those regions. Hallier (I.e.) already pointed out this fact: "Von V.sambu- cinum Reinw. sind die Exemplare mit ganzrandigen Slattern leicht zu unterscheiden durch ihre nicht mit bleichen Lenticellen langs gestrichelten jungen Zweige, ihre oberseits harzglanzenden jungen Blatter, ihre kahlen, harzglanzenden Fruchtknoten und ihre in der Knospe nicht kugeligen, . sondern langlichen Blumenkronen". However, the discrimination cannot becalled easy. In flowering specimens the ovoid flower-bud, the tubular corolla, the inf lexed stamens, the lepidote or vernicose ovary point to 118 R E I N W A E D T I A [VOL. 1 V. coriaceum; in fruiting specimens the small, young somewhat lepidote or shining .vernicose drupes are characteristic. In V. sambucinum of the Lesser Sunda Islands, however, the ovary is often but sparingly hairy, the flower-bud more ovoid than in Javanese specimens, and the twisted aestivation of the stamens often indistinct. I agree with Hallier's opinion that Fawcett's V. forbesii must be referred to V. sambucinum: it is the more or less aberrant form, which occurs in Timor. On the contrary tha poor specimens of Forbes 3872 belong in my opinion to V. coriaceum. Fawcett regarded them as a new species or a variety of his V. forbesii; Hallier identified them as V. sambucinum. The specimen Koorders 1065/? (cf. Koorders & Valeton op. cit. 39; is, in my opinion, not a Viburnum, but a species of Maesa. As far as I know Hooker f. & Thomson were the first to treat V. cy- Undricum Ham. ex D. Don and V. coriaceum Bl. as synonyms. V. cylindri- cum was published in the "Prodromus florae nepalensis" with the follow- ing diagnosis: "foliis ovali-oblongis acuminatis coriaceis integerrimis subtus ramulisque pubes- centibus, cymis compositis erectis tomeritosis, corollis oblongis tubulatis: limbo brevissi- mo 5-dentato". — D. Don (Prodr. PI. nep. 142. 1825). I greatly doubt whether the Nepal plant with entire leaves, pubescent 'beneath, and tomentose cymes can be identical with the Malaysian Vibur- num coriaceum. Therefore, I prefer for the present to use Blume's un- ambiguous name. S P E C I M E N S E X A M I N E D . — S U M A T R A . W i t h o u t e x a c t l o c a l i t y : Korthals g-n. ( L ) .

Branches and branchlets brownish, glabrous, warty-lenticellate. Petioles channelled above, glabrous, 1.5—3.5 cm long. Leaf-blades coria- ceous, dark green above, bright green beneath, upper side glabrous, under side minutely gland-dotted and with a distinct elliptic glandular pit at the base on both sides of the midrib and often smaller pits in the nerve- axils, elliptic, obovate or ovate, 8—15 cm long, 5—-8 cm wide; apex obtuse or shortly and bluntly acuminate, rarely somewhat emarginate, base cuneate to nearly rounded, somewhat decurrent on the petiole, margin entire, revolute in dry state; midrib impressed above, prominent beneath; primary side-nerves much less prominent, 4—8 on each side of the midrib, at an angle of 45—60° to it, ascending, arcuately anastomosing near the margin, veins distinct, reticulate. Inflorescence terminal, corymbiform, 3—4 times umbellately branched, 6—12 cm across, infructescence up to 15 cm; young axes rather densely brown stellate-pubescent, glabrescent; peduncle rather stout, up to 12 cm long; primary rays 5—7(—8), 2—5 cm long, later on up to 6 cm; bracts and bracteoles small, linear-lanceolate, rusty stellate-pubescent, very soon caducous. Calyx-limb cupulate, obscure- ly lobed, minutely gland-ciliolate, otherwise glabrous. Corolla tubular, obovoid-ellipsoid in bud, white; tube 3—4 mm long, lobes erect, rounded to rather acute, minutely gland-ciliolate, 1 mm long. Stamens long-exsert- ed; filaments flattened, subulately tapering towards the top, in the flower- bud with inflexed top, inserted at the base of the corolla, glabrous, 7—8 mm long; anthers oblong, purplish, about 2 mm long. Ovary cylindrical, glabrous, about 2 mm long; style conical, glabrous, 1 mm long. Drupe ovate, dorsiventrally compressed, (young) bluish green, 9—10 mm long, 6—7 mm wide, endocarp undulate in cross-section, shallowly 2-grooved on the dorsal side, shallowly 1-grooved on the ventral side. ECOLOGY. — In forests and thickets in the higher mountain regions. DISTRIBUTION. — Only known from the Malay Peninsula and Sumatra. The original description of this species by Gamble was made after an incomplete specimen of Scortechini (no. 375b) from Perak The char- acters of V. beccarii given in Ridley's "Flora of the Malay Peninsula- die nearly the same as in Gamble's description; new localities have not 122 R E I N W A R D T I A [VOL. 1 been recorded since. The occurrence of the species in Sumatra was already mentioned by Gamble: Mt. Singgalan (Beccari 194 in Herb. Kew; also in Herb. Lugd. Bat.!), In the various herbaria I found material from several new localities in Sumatra, some of them bearing flowers and nearly mature fruits. Van Steenis 9960 differs somewhat from the other specimens by its less stellate-pubescent, more tender axes of the inflorescence, but in my opinion it cannot be referred to another species. The shape of the corolla and the aestivation of the stamens point to a close relationship between V. coriaeeum and V. beccarii. SPECIMENS EXAMINED. MALAY PENINSULA.

In order to come to a satisfactory classification of the group of V. glaberrimum, occurring in the Philippines (species 3—5), it will be neces- sary to collect a lot of additional specimens, with both flowers and fruits from the same plant, as the material in the herbaria is insufficient to gain an insight in this difficult question. Viburnum- glaberrimum was described in 1909. As Merrill mentions, it is a species manifestly allied to V. coriaceum of the Indo-Malayan region, but at the same time very distinct, especially in its vegetative characters. I did not see the type of V. glaberrimum, Merritt 15848, but in his "Enu- meration" Merrill also mentions Merr. Phil. PI. 1519, of which I have seen several sheets in the various herbaria. It will be useful to verify the characters given by Merrill. In my opinion V. glaberrimum cannot be called "glabrous throughout." Not only the glands of the nerve-axils on the under side of the leaves are often somewhat bearded, but also the axes of the inflorescence are thinly stellately pubescent, though glabres- cent. The leaves are rather elliptic or ovate than obovate. The corolla is not 5 mm but 4 mm long, the tube being about 2.5 mm, the lobes about 1-5 mm. The filaments are not 5 mm long but 6 mm. Moreover, I do not 126 R E I N W A R D T I A [VOL. 1 believe that the leaves of V. glaberrimum are always entire. In Loher 13878 and 13904, otherwise quite identical with Merrill Phil. PI. 1519, the leaves are distinctly remotely undulate-dentate. However, V. glaberrimum and V. coriaceum differ manifestly. Where- as in V. coriaceum the leaves are usually ovate-lanceolate, gradually long-acuminate and remotely dentate, they are broader, elliptic to ovate, not or obtusely short-acuminate, entire or somewhat undulate in V. gla- berrimum. The corolla of V. coriaceum is more distinctly tubular than with V. glaberrimum, the tube in the former being at least 3 mm, often longer, the teeth 1 mm, in the latter respectively 2.5 and 1.5 mm. The flower-bud of V. glaberrimum is obovoid, with V. coriaceum more ellip- soid. The stamens of V. glaberrimum are inserted at the base of the corolla, those of V. coriaceum somewhat adnate to the tube (0.5—1 mm, sometimes, even to 2—3 mm above the base). The filaments are 6 mm long; those of V. coriaceum reach this length only in some large-flowered specimens. Obviously the place of V. coriaceum, which is wanting in the Philippines, is taken by V. glaberrimum, and the differences are presum- ably sufficient to justify the specific separation from the variable V. coria- ceum. Later on Merrill published two further species, viz. V. platyphyllum (1915) and V. cornutidens (1925); according to their author the former is distinguished by its much larger, distinctly slenderly acuminate leaves, the latter by its conspicuously corniculate-dentate leaves. For the rest no striking differences are given. V. platyphyllum is based on Wenzel 923 from Leyte, V. cornutidens on Ramos & Edafio 40309 from Luzon. In Merrill's "Enumeration" no supplementary specimens of both species are mentioned. Viburnum cornutidens has been described from a fruiting specimen only. In comparing it with V. glaberrimum, Merrill Phil. PI. 1519, I have been unable to find other valid differences but the dentation of the leaf. In my opinion it would be undesirable to segregate it specifically from V. glaberrimum, until further collections have furnished more characteris- tics. For a similar variation of the dentation (entire, undulate, dentate) can be observed in the Philippine V. odoratissimum, without this having led to the institution of a separate species. On the other hand it must be admitted, that the thickly coriaceous, broad, dentate leaves are striking. The plant also seems to be characterized by the broadly ovate fruits, which measure about 8 by 6—7 mm, those of V. glaberrimum probably being smaller (see below). 1951] KERN: Viburnum in Malaysia 127 We have a similar case in V. platyphyllum. The much larger leaves, gradually tapering upward to the distinctly slenderly acuminate apex in the type are indeed remarkable. The inflorescence is larger too and, as far as I can judge from a single specimen, there are also slight differences in the flower. The calyx-teeth seem to be more distinct, the corolla appears to be somewhat widened towards the top, therefore less tubular than in V. glaberrimum, and more globular in bud. Unfortunately fruits are absent, both in Merrill Phil. PI. 1519 and in Wenzel 913. I have met with great difficulties in trying to identify the specimens not mentioned by Merrill. Loher 13904 and 14846, both distributed as V. glaberrimum, have been correctly identified in my opinion. Ramos & fEdano 39025, distributed as V-. odoratissimum Ker, I also take for V. gla- 'yerrimum. The fruits of this specimen are nearly orbicular, 5 by 5 mm, at probably not full-grown. Ramos 41482 and 41585 on the contrary iear ovate young fruits of 6—7 by 4—5 mm. The leaves, although much -smaller than in Wenzel 923, taper more or less gradually into the rather long acumen. For these reasons I can agree with the determination on the label as a small-leafed form of V. platyphyllum. But I repeat, the 'question is very intricate. For the present I must acquiesce in the opinion M Merrill; it is to be hoped that more complete material may offer a lolution. 6. VIBURNUM PUNCTATUM Ham. ex D. Don Viburnum punctatum Hamilton ex D.

DISTRIBUTION. — SE Asia, from Nepal, Kumaon, and the Deccan to Siam and Indochina. In Malaysia only collected twice at neighbouring localities in North Sumatra. The statement of Hooker f. & Thomson (I.e.) : "Java," already doubted by Hallier for phytogeographic reasons, has never been proved by any material. Don's meagre diagnosis of V. punetatum reads: "foliis ovali-oblongis integerrimis mucronulatis utrinque glabris, cymo terminali laevi patente sessili." It is to be found again nearly literally in De Candolle's "Pro- dromus," only with the addition "foliis ... subtus sub lente punctatis." The description of V. acuminatum in the "Prodromus" is also very short and it is impossible to find a clear difference between the two diagnoses. Consequently Hooker f. & Thomson united the two species, treating the name V. acuminatum in synonymy. Nearly all later authors followed them, recently Merrill, who expressly stated: " [Bangham 825] very closely matches Wallich's Nepal material and Wight 1523, distributed as V. acu- minatum Wallich." However, Clarke distinguished the Deccan plant from the Nepal V. punetatum as variety acuminatum (Wall.) Clarke, character- ized by its acuminate leaves, persistent bracts, larger drupes and ob- scurely grooved seeds, adding: "the berry looks so different that it may indicate a distinct species." The group of V. punetatum obviously com- prises a number of closely related taxa and great prudence should be exercised in uniting them into a single species. Viburnum lepidotulum Merr. & Chun (in Sunyatsenia 2: 22 pi. 12. 1934), for instance is undoubt- edly a markedly different species, although judging from the description and the plate it seems to differ only from the plant figured in Wight's tabula 1021, by its larger fruits [in How 72851 (B) they are even 18 mm long!]- The conspecifity of V. acuminatum and V. punetatum is therefore in my opinion still questionable, but provisionally I follow the majority of the authors. At any rate the Sumatran specimens agree with Clarke's variety acuminatum and with Wight's plate. They are identical with the Indian and Siamese specimens I saw [Wight 1263 (L); Nilgiris, Clarke B 10744 (B) ; Pulney Hills, Sauliere 74, 123 (B) ; — Pu Tong, Kerr 8874 (S) ; Chiengmai, Kerr 6222 (S) ; Krabin, Kerr 9829 (S) ].

DISTRIBUTION. — Siam, Malay Peninsula, Sumatra; the typical form probably restricted to higher altitudes (800—1200 m). Like most Malaysian Viburna this species is very variable in all its parts, especially as to the indument. Almost glabrous forms occur as well as densely pubescent ones. This variability more than once led to the distinction of new segregate species. The nearly glabrous plants for in- stance were described by Ridley as V. longistamineum from the Malay Peninsula. I am unable to draw a line between V. sambucinum, also occur- ring in the Malay Peninsula, and V. longistamineum. I take this for a somewhat slender, more glabrous form. Ridley named his species after "the very long projecting stamens," but this feature is also peculiar to V. sambucinum sensu .strieto and the difference is illusory. In my opinion V. longistamineum is perhaps not even a well-marked variety. The pubescent form, on the other hand, also received some specific names. When Miquel described his V. swmatranum after a specimen col- lected by Junghuhn at Sipirok, he did not know the flowers. He added to the description: "Probabiliter prope V. sambucinum inserendum, indu- mento persistente insigne." The description indeed does not preclude the close relationship with V. sambucinum; there is even only one character in it, which is not applicable to the common form of this species, viz. the indument of the leaves. The full-grown leaves of typical V. sambucinum are almost glabrous on both sides, except for a few hairs on the nerves and the bearded nerve-axils on the under side; the young ones, however, are pubescent benath, especially on the midrib and the primary side-nerves. In V. swmatranum the under side of the full-grown leaves is softly villous with persistent hairs. In the various herbaria I found several specimens of a Viburnum, fully agreeing with Miquel's description and the type. Some of them bear flowers, but nevertheless I am unable to find differ- ences from V. sambucinum that may be considered specific. Moreover, the hairiness of the leaves is very variable, slight, for instance, in Krukoff 4201 and 4366, and Yates 2544. I agree with Hallier who reduced V. sumatranum to a variety of V. sambucinum. Presumably the range of this variety (or geographic race) extends from Siam through Malaya to Sumatra. Viburnum villosum Ridl. of the Malay Peninsula is quite iden- tical with Miquel's plant. Ridley described the flowers as follows: "Flow- ers small sessile green . . . . Corolla tube short Vio inch long glabrous cylindric thick lobes rounded ovate, as long as the tube 5. Stamens twice as long as the corolla 5." This description is incorrect. I cannot find any 1951] KERN: Viburnum in Malaysia 133 evident difference with the corolla of V. sambucinum. The tube and the lobes are both about 1 mm long, the stamens about 6 mm. Besides, the label-note "flowers green" must probably be due to the fact that only flower-buds are present. King already mentioned a more hairy form from the Malay Peninsula. Obviously he did not know the densely villous plants, which are indeed very striking. However, there are so many intermediate specimens that I cannot maintain it as a species. For lack of authentic material I cannot quite make up mind, but judging from Craib's description and a specimen in the Rijksherbarium at Leiden (Lugd. Bat. 934.323—409) I am nearly convinced that V. inopi- natum Craib from Siam in future must also be treated as a synonym. Craib published V. inopinatum as a new species in his "Contributions to the flora of Siam." He already saw the close relationship with V. sambu- cinum, for his description begins: "a V.sambucino, Reinw., foliis subtus molliter pubescentibus, calycis dentibus minoribus, corolla parum majore, filamentis antherisque longioribus recedit." In the Malaysian specimens, however, the corolla is not larger than in V. sambucinum, the tube being about 1 mm, the lobes fully 1 mm long, neither can I find evident differ- ences in the calyx-lobes. The length of the fully developed filaments in V. sambucinum is very variable, from 4—7 mm. In Henderson 11555 I even measured filaments of 8—9 mm. In general the specimens of Su- matra and the Malay Peninsula have stamens projecting further than with those of the eastern part of the Archipelago (Celebes, Lesser Sunda Islands). In comparing the descriptions of V. inopinatum and V. sambucinum in Danguy's elaboration in Lecomte, "Flore generale de l'Indo-China" one only finds the following differences: V. inopinatum Limbe glabre en dessus, excepte la nervure mediane, pubescent en dessous. Inflorescence pubescente, rayons a poils : surtout etoiles et blanchatres. Fleurs blanches. Calice a 5 dents courtes, a peine 0,5 mm,, pubescentes. Tube [de la corolle] 1,5 mm. Pilet 5—6,5 mm. V. sambucinum Limbe glabre sur les 2 faces. Rayons pubescents, couvert de poils etales, a la fin glabrescents. Fleurs jaunatres. Calice a 5 dents triangulaires, obtuses, glabres, 1 mm a peine. Tube tres court, 0,5 mm. Filet 5 mm. sub- It may be that the Siamese plants differ in all these characters and represent a separate species, but it is clear, that the data on V. in- atum are taken unaltered from Craib's description. So I do not Relieve that the contrast "fleurs blanches — fleurs jaunatres" really 134 R E I N W A R D T I A [VOL. 1 exists. "Tube tres court, 0,5 mm" in V'.: sambucinum does not at all agree with the numerous specimens of this species examined by me. They all have a corolla-tube of at least 1 mm in length. Viburnum sambucinum of Hosseus (I.e.) from Siam, Chieng Mai, no 250 (L) is also variety tomen- tosum.- It is remarkable that Clarke (I.e.) under V. sambucinum mentions: "Leaves in some Javan specimens are hairy beneath." None of the Java- nese specimens of that species I examined showed this; on the contrary I did not see quite typical V. sambucinum from North Sumatra, whereas but a single specimen of variety tomentosum has been collected in South Sumatra. . In the list below the specimens with more or less persistent pubes- cence have all been reduced to variety tomentosum; the typical specimens are marked by an asterisk (*) ; the latter probably only occur at higher elevations above sea-leavel (ef. the label-notes).

C e n t r a l B o r n e o . Amai Ambit, young fr., 1893-1894, Hallier f. 3272 (B, L). The extremely difficult group of Bornean Viburna nos. 8—9 could be but provisionally worked out. The material was gathered mainly by J. & M. S. Clemens during the Kinabalu-expeditions of 1931, 1932, and 1933. A single number with very young fruits was collected by Hallier in 1893—1894. Also Gibbs 3990, the type-specimen of Viburnum verni- cosum, collected in 1910, belongs to this group. I did not see this specimen. Because Miss Gibbs ascribed filaments of 2 cm in length to it, I at first believed it must be a very deviating species. The photographs, which I received through the kindness of Dr Taylor of the British Museum, how- ever, convinced me, that Hallier 3272 and Clemens 27033, 28263, 30298 are identical with it. The above description was made only after these specimens. On purpose I did not include the other numbers mentioned below, because they constitute some fairly marked groups, which in future may possibly be segregated. For the present I confine myself to stating the differences. Clemens 30885, 32225, 32752, and 40166 deviate on account of the thickly coriaceous, manifestly obovate, short-acuminate leaves (the acumen at most 3 mm,long), but especially on account of the large, elliptic fruits, 12—14 mm long, 7—8 mm wide. Clemens 30767 possesses broad-elliptic leaves, 14—16 cm long, 9—11 cm wide. Flowers are absent, but the texture of the leaves, the shape of the infructescence, the size of the fruits and the like, point to a close relationship with Clemens 30885, etc. The lower primary nerves arise at an angle of about 60°, the higher ones at an angle of about 45°. The upper surface of the leaves bears scattered, short, white, at the base scale- like dilated hairs; some of the latter along the midrib and the primary side-nerves are black. Less deviating is Clemens 33761, striking on account of its large ovate fruits, 12 mm long, 10 mm wide. Whether all these forms can be maintained under the polymorphous Viburnum vernicosum requires further scrutiny. 142 R E I N W A R D T I A [VOL. 1 1951] KERN: Viburnum in Malaysia 143 The thick, long projecting stamens of the group are characteristic. The filaments are twisted in the flower-bud; this aestivation points to a relationship with Viburnum sambucinum, with which the Bornean plants also rather coincide as to the shape of the leaf, corolla, fruit, etc. Viburnum sambucinum is easily distinguished by its pubescent ovary, the stellate-pubescent axes of the inflorescence, and its almost filiform filaments. Viburnum beccarii of the Malay Peninsula and Sumatra also coin- cides in its habit with the species of this group. It can easily be distin- guished by the tubular corolla, the nearly ellipsoid flower-buds, the shorter, not twisted filaments, the somewhat smaller fruits, and by the much less prominent primary side-nerves on the under side of the leaves. The glandular pits at the base of the leaves characterize both Viburnum, beccarii and V. vernicosum; they are absent in V. hispidulum; in V. sam- bucinum they are reduced to spotty glands. 10.

Evergreen, crooked, sometimes sprawling shrub or small, vaguely branched tree, up to 10 m, usually much lower. Trunk terete, unknotted, un- buttressed; bark smooth, greyish; youngest parts thinly stellate-pubescent, glabrescent. Branchlets terete, lenticellate, glabrous. Petioles channelled above, thinly stellate-pubescent, glabrescent, 1—2 cm long.. Leaf-blades thinly coriaceous, bright green above, pale green beneath, when dried dark brown above, yellowish brown beneath, glabrous on the upper side, thinly stellate-pubescent to almost glabrous on the under side, very variable in shape, broad-elliptic, ovate or oblong-elliptic, up to 18 cm long and 10 cm wide; apex short-acuminate, base nearly rounded to cuneate and somewhat decurrent on the petiole, margin in the upper 2/3 coarsely crenate-serrate to finely serrate, teeth shortly mucronate, the lower 1/3 entire or supercifially dentate; nervation indistinct above, rather promin- ent beneath; primary side-nerves 5—8 on each side of the midrib, arcuately ascending, evanescent and indistinctly anastomosing near the . margin, connected by delicate veins. Inflorescence terminal (or sometimes spuriously lateral), paniculate, short-pyramidal, 3—4 times paniculately branched, 5—9 cm across, 5—7(—10) cm long, with stellate-pubescent, glabrescent axes; peduncle 4—10 cm long; primary branches 4—7, ver- ticillate; bracts sometimes leafy, bracteoles minute, lanceolate, stellate- pubescent, 1 mm long. Flowers somewhat fragrant, 4—5 mm wide. Calyx- teeth ovate-triangular, glabrous or somewhat pubescent, green, 0.75 mm long. Corolla globular in bud, nearly rotate (only slightly campanulate) when open, creamy white, glabrous; tube 0.75—1 mm long, lobes ovate, rounded, 1.25- -1.5 (sometimes almost 2) mm. Stamens somewhat exserted; filaments inserted near the base of the corolla, flattened, subulately tapering towards the top, in bud with inflexed top, white, 2—3 mm long; anthers elliptic, sordidly white, about 1 mm long. Ovary cylindrical, glabrous, 1—-1.5 mm long;- style short and thick, 1—1.5 mm long. Drupe oblong-ellipsoid, somewhat oblique, slightly compressed, turning from bright green through red to purplish-black, usually 7—10 mm long and 4—5 mm wide; endocarp undulate in cross-section, with 2 dorsal and 1 ventral groove. ECOLOGY. — In primary and secondary forests, in brushwood, often common but scattered, usually between-500 and 1500 m altitude, rarely lower (lowest record 150 m) or higher (one record of 2400 m, from Mt. Patuha). Flowering and fruiting throughout the year. USES. — Sometimes cultivated as a hedge-plant, easily multipliable by cuttings. Other uses not recorded; not fit for timber. The ripe fruits are readily eaten by birds. DISTRIBUTION. — SE Asia. In Malaysia only in the western part, from the Malay Peninsula (here local) through the whole of Sumatra and Java up to Bali and Lombok. Also collected in Borneo a few times. An extremely variable species, mainly as to the shape of the leaves and the size of the fruits. Authentic specimens of Viburnum monogynum Bl. in the Leiden Herbarium prove, that this is merely a form with super- ficially toothed leaves. Miquel (1856) distinguished three forms of V. sun- daicum: a. macrodon Miq.: folia nisi omnia, saltem in eodem ramo plura grosse serrata, oblonga vel elliptica (V. lutescens Bl., s.s.); (S. latifolia Miq.: folia pleraque ovato- vel lato-elliptica1; y. microdon Miq.: folia oblonga vel elliptica, tenuiter serrulata vel superne saltem serrulata aut repanda vel in eodem ramo subintegerrima (V. monogynum Bl.). He himself already stated, as well as Koorders & Valeton later on, that these forms are 1 = Viburnum lutescens var. latifolium (Miq.) Hochr. in Candollea 5: 287. 1934. 144 R E 1 N W A R D T I A [VOL. i 1951] KERN': Viburnum in Malaysia 145 connected by numerous intermediates. Although it is likely that in future Viburnum lutescens will be divided into various races, I do not believe that Miquel's forms are of any systematic value. Very striking is the variability as to the size of the fruit. In Borneo, Hallier collected a specimen of a Viburnum, which I might consider to be V. lutescens, deviating however from the Javanese plants by its much larger, more flattened, broader fruits, 11—12 mm long, 7—8 mm wide. These large fruits I also found in some specimens from the Malay Peninsula (Henderson 11496, Henderson & Nur 11202, Ridley 13902), which also otherwise agree with Hallier's plant. The leaves are very minutely denticulate. However, also in Java and Sumatra plants occur with hardly denticulate leaves, but with typical fruits. Moreover, in Van Steenis 5923 from Atjeh I found fruits 11—12 mm in length but only 5 mm wide. Therefore I am not inclined for the present to segregate a variety with large fruits. The question whether Viburnum colebrookianum Wall, from the Himalayan region should be united with the Malaysian Viburnum lutes- cens or not seems to be still open. Hooker f. and Thomson mention the Indian plant as Viburnum lutescens Bl., introducing V. colebrookianum as a synonym. Maximowicz, however, is of the opinion that V. colebroo- kianum differs from V. lutescens "corymbis subaphyllis axillaribus foliis fere a basi granduisque serratis et drupa duplo minore ovata." Clarke distinguished the two species as follows: V. colebrookianum: corymbs on very short axillary branches, drupe ellipsoid, 1/5 by 1/6 in., seed hardly grooved; V. lutescens: inflorescence terminal, berries • 1/3 in. long, narrowly obovoid- oblong, with deeply grooved seed. Koorders & Valeton also treated Viburnum colebrookianum as a separate species: "foliis et inflorescentia valde similis sed ... endocarpium vix sulcatum, albumen aequabile." I only saw a few incomplete specimens of Himalayan Viburnum colebrookianum. I could not find any differences with V. lutescens as to the flowers. As the leaves of the latter are very variable, those of the Himalayan plants are not particularly striking. However, the short-stalked pseudaxillary inflorescences are remarkable indeed, although they are not completely lacking in Malaysian Viburnum lutescens. The small fruits with their less grooved endocarps are always characteristic and for the time being I take Viburnum colebrookianum and V. lutescens to be two very closely allied species. Surely the specimens from Kwantung, Hainan, Ton- kin and Indochina I saw (Lei 246, How 72981, 73407, Balansa 4422, Squires 184, Tsiang Ying 1940, Petelot 6294), all distributed as V.colebroo-- kianum do not differ specifically from V. lutescens. It is also clear in my opinion, that the Indochinese plant, described by Danguy in the "Flore generale de l'lndochine" as V. colebrookianum is in reality V. lutescens. "Inflorescences terminales ... Fruit ovale-aigu, long de 6—8 mm ... noyau presentant un sillon sur la face ventrale, 2 sur la face dorsale", can only refer to this species. By the way it may be noted that the measurements of the flower given by Danguy (tube 1.5 mm, lobes 2.5 mm) and "ovaire legerement pubescent," do not agree with any of the Indochinese speci- mens examined.

ECOLOGY. — In forests, obviously restricted to the higher mountain [regions, from 2300 m upward. The description of Miquel runs as follows:— "Arboreum, ramuli tetragoni, (an juniores etiam?) glabri, petioli 1—fere 1% pollicares antice canaliculati, folia obverse oblonga usque lato-elliptica brevi-acuminata 148 R E 1 N W A R D T I A [VOL. 1 1951] KERN: Viburnum in Malaysia 149 vel obtusa, supra basin acutam vel subacutam vulgo inaequalem dense aequaliter gros- siuscule serrata, coriacea, supra nitida, subtus pallida nunc glaberrima ad lentem minute verrucellosa, costulis 6—7 adscendentibus demum transverse venosis pertensa, 4—1% poll, longa, thyrsi ramulos terminantes, ramis primariis 5—7 verticillatis superne subpaniculato-ramulosis, bracteae bracteolaeque lanceolatae, flores in ramulis ultimis sessiles subconferti, baccae obovoideae vel ellipticae angulato-compressae, dentibus calycis 5 ovatis concavis brevibus stigmateque subsessili coronatae". — Miquel (PL Ind. bat. 2: 123. 1856). This description is rather insufficient for the identification of the plant. Up to the present little is known about Viburnum junghuhnii, undoubtedly a well-marked species. Koorders & Valeton in their "Bijdra- gen tot de kennis der boomsoorten op Java" (Contributions to the know- ledge of the trees in Java) cite Miquel's description. They add that neither in the description nor in,the authentic specimen of Junghuhn, in which flowers and fruits were said to be absent, could they find an essential difference with Viburnum sundaicum Miq. (= V. lutescens Bl.) ; only the leaves were small and the inflorescence quite glabrous; Junghuhn's plant originating from Mt. Dieng in Central Java had not yet been traced again in that locality. They suppose that it is not out of the question, that a few sterile specimens of Viburnum, collected in Central Java, may belong to this species ("or variety"). From what they say it is clear, that Viburnum junghuhnii must greatly resemble Viburnum lutescens. Miss G. J. A.. Amshoff in her elaboration of the genus Viburnum in Backer's "Beknopte Flora van Java," (Nooduitgave, fam. 175: 4. 1945) has contributed much to the solution of the question. She has found a Viburnum, originating from West-Java, which might easily be confounded with V. lutescens. She takes it for V. junghuhnii, and I can wholly agree with her. She did not see the flowers, but in the fruits she has found a difference with V. lutescens, described as follows: "Endocarp nearly plane on the dorsal side, on the ventral side with a deep, in cross-section bilobate groove." Among the material of Viburnum lutescens in Herbarium Bogoriense I found some further specimens, fully answering to this description. Com- parison with Junghuhn's type-specimen which does bear fruits, has convinced me of the correctness of Miss Amshoff's interpretation. The specimen Lorzing 609 bears one rather young inflorescence; as far as I can judge from the few flowers I could examine they also resemble those of Viburnum lutescens. They are somewhat larger than is usual in the latter, the ovary being about 2 mm long, the corolla 3 mm. The filaments are somewhat stouter, the anthers larger. Whereas in Viburnum lustecens the filaments are inserted near the base of the corolla, in V. junghuhnii they are distinctly adnate to the tube in the 150 REINWARDTIA [VOL. i lower 0.5—1 mm. The shape of the fruit is undoubtedly different from that of V. luteseens, not oblong, but shorter, obovate. Notwithstanding the different cross-section of the endocarp, Viburnum junghuhnii may be allied to V. luteseens, but on the other hand the affinity to the Viburnums with incurved endocarp cannot be denied. The endocarp of V. junghuhnii is both undulate and incurved. The insertion of the filaments also seems to point to the latter relationship. The leaves of Viburnum junghuhnii are more coriaceous than those of V. luteseens, but this cannot easily be judged from dried material. The primary nerves are generally more prominent than in V. luteseens. The inflorescence is not quite glabrous; the axes are more or less stellate-pubescent, at least in a young stage. Lorzing evidently saw the differences with V. luteseens. To his spec- imen 472 of V. luteseens he added: "Under no. 472 a branchlet, which is similar to this species. The find-spot has escaped my memory, although 1 am nearly sure, that it originates from more than 1700 m altitude, quite possibly from N Sundoro, about 2600 m. Vide no 609." Both 472a and 609 are indeed V. junghuhnii. SPECIMENS EXAMINED. — SUMATRA. W e s t C o a s t . Mt. Korintji, cloud forest, 2700 m, shrub, fruits red, fr., Aug. 1931, Frey Wyssling 108 (B). — JAVA.

The above description only refers to the Malaysian material. In studying the specimens of Viburnum odoratissimum in Herbarium Bo- goriense I was much surprised to see that the descriptions of most of the authors are not quite applicable to the Malaysian form. The main differ- ences concern the shape and the dimensions of the corolla. Some of those descriptions I may cite here. Viburnum odoratissimum has been described as a new species by Ker-Gawler, in 1820. According to him the corolla is rather fleshy, turbin- ately rotate, white, caducous, turning yellow or buff as it fades, tube three times the length of the calyx or more, with an open dilated orifice, limb rather longer than the tube, revolutely reflexed in the end, segments rounded convex, the filaments adnate to the tube, divaricate, equal to FIG. 9. Viburnum, odoratissimum Ker-Gawl.: a, corolla of Chun 5216 (Hongkong); 6, same of Elmer 16965 (Philippines) ; c, same of Maximowicz s.n. (Yokohama). the limb, subulate, white, stiff, permanent. In De Candolle's "Prodromus" Viburnum odoratissimum is found under the heading "corollae rotatae aut vix subcampaniformis." Hooker f. & Thomson also say: "corolla par- va, rotata." Oersted divided the genus Viburnum into five genera; concern- ing the corolla of his genus Microtinus, to which Viburnum odoratissimum is referred, he says: "corolla parva, rotata, quinquefido, lobis obtusis." I also draw attention to his description of the stamens: "stamina quinque immo tubo inserta." Danguy described the corolla as "blanche, rotacee, sub-campanulee, glabre, tube de 1,5 mm, lobes de 2,5 mm, obtus, etales" and the filament as "long de 3—4 mm, insere vers le milieu du tube de la corolle." The corolla in at least the greater part of the Malaysian specimens, however, cannot be called rotate and hardly subcampanulate. The tube being about 3 mm, somewhat widened upward, the lobes about 2 mm, spreading horizontally in full flower, finally reflexed, it is shortly salver- shaped rather than rotate-subcampanulate. The filaments are about 2 mm long, adnate to the throat of the corolla. K. Koch distinguished two related species, Viburnum odoratissimum s.s. and V. awabuki K. Koch, the latter with "rundlichen, flach ausgebrei- teten Abschnitten kiirzer als die Blumenrohre, wahrend sie bei dem na- hestehenden V. odoratissimum langer erscheinen." In spite of the asser- tions of Maximowicz and Rehder I was at first inclined to believe that the Malaysian plants are not conspecific with Ker's Viburnum odoratissimum, but that they might belong to V. awabuki. Maximowicz in his enumeration of the Viburnum-species of Eastern Asia, discussing the taxonomic value of the different organs, asserts: "Nee magis ad sectiones stabiliendas valet corollae forma, dum adsunt species flore absente nequaquam distinguen- dae, dum adest imo una (V. odoratissimum) ubi corolla variat subrotata et tubulosa." (op. cit., p. 644). On page 50 he argues that the two species, distinguished by Koch, cannot be maintained, as the plant of Kiusiu seen by him is intermediate between the Nippon specimen with the tube twice as long as the limb, and the Lutschu specimen with the tube shorter than the limb. Rehder, in Sargent's "Trees and Shrubs," also ascribes to Viburnum odoratissimum a rotate or campanulate corolla. According to him the northern .form, in which the tube of the corolla is longer than the limb, distinguished by K. Koch as Viburnum awabuki, is hardly well marked enough to deserve varietal rank. No more than with actual V. odoratissimum do the Malaysian spec- imens agree with the Japanese plants, in which the tube of the corolla is still longer. In Nakai's "Tentamen systematis Caprifoliacearum japonicarum," 1921, Viburnum odoratissimum s.l. is divided into three species, the new V. liukiuense being intermediate between V. odoratissimum s.s. and V. awabuki. The differences given between V. odoratissimum and V. liukiu- ense did not convince me that the latter should deserve specific rank. It is said to differ in its evanescent pith, the more persistent bracteoles, the more shining leaves, and the reddish branchlets and petioles; like V. odoratissimum it has a depressed conical inflorescence and a short tube of the corolla. I must confess my inability to decide whether the Malay- sian plants are identical with V. liukiuense or not. In my opinion even the leaves of the Chinese specimens I examined are more shining than those of the Malaysian ones. These seem to agree completely with Viburnum arboricolum Hayata. The flower represented in "Icones plantarum for- 156 R E I N W A R D T I A [VOL. 1 1951] KERN : Viburnum in Malaysia mosanarum" (4: t. 1 fig. 2. 1914), is identical with that of the common Malaysian form; the description, too, could have been prepared after a Malaysian specimen: "corolla cylindrico-campanulata utraque glabra 5 nim longa, tubo 3 mm longo totiusque lato, lobis late cordato-rotundatis 2 mm longis totiusque latis apice rotundatis basi cordatis, partibus cor- datis imbricatis margine integris vel obscure crenulatis." In comparing V. arboricolum with V. odoratissimum Hayata mentions only the darker green lusterless leaves. It is curious that Nakai, on the contrary, ascribes dull leaves to V. odoratissimum. Indeed he cites V. arboricolum as a synonym of V. odoratissimum, this, however, in spite of the fact that the tube of the corolla is longer than the limb. On his "Tabula distribu- tionis" (op. cit., p. 121), the Philippine plant is also considered by Nakai as Viburnum odoratissimum. Elmer described his number 22336 from Mt. Pinatubo, Luzon, as a new species, Viburnum zambalense. It is not clear whether he regards all Philippine 'odoratissimum' as belonging to his new species or only those with entire leaves. At any rate it is impossible to separate Elmer 22336 specifically from the other Philippine specimens. His description of the flower is correct, probably except for the statement "up to 8 mm in length," for I never saw such large flowers in any Philippine specimen and the flowers of Elmer's type-specimen do not deviate from the common form. The shape of the leaves is extremely variable. Instructive in this respect is for instance Ramos & Edano 40460, with clearly toothed and entire, long- and short-acuminate, rounded and somewhat emarginate, obovate and elliptic-lanceolate leaves in one specimen. Chinese Viburnum odoratissimum has indeed a more rotate-campanul- ate corolla, the tube being about 1.5 mm, the spreading lobes about 2 mm long. Yet the difference with the Malaysian and Formosan plants in this respect is not so great as it seems to be, for there are Philippine spec- imens, although rare, with the tube equal to the limb. In the Chinese form too the filaments are adnate to the throat of the corolla. • Summarizing I am of opinion that the separation of Viburnum liukiuense, V. arboricolum, and V. zambalense has not contributed to the solution of the difficulties in this group. For the present I regard them as belonging to the polymorphous species Viburnum odoratissimum. The continental plants can perhaps be segregated on account of the length of the tube of the corolla and the indument, but then the insular ones un- doubtedly still contain several races, which may be recognized only by a comparative study of extensive material from the whole area. 157 SPECIMENS EXAMINED. — JAVA.

DISTRIBUTION. — China (Hupeh), Formosa. In Malaysia only in the Philippines (Luzon). The triple-nerved leaf with marginal glands (reminding one of those in Faccmmm-species), the hairy tube of the corolla, the achenoid drupe and the peculiar cross-section of the endocarp characterize this species and separate it from the other Malaysian species of Viburnum. Elmer mentions in connection with his Viburnum valerianicum that the strong odour, especially in cured specimens, is that of Valeriana. The same fact was already stated by Hallier in dried specimens of Viburnum sambu- cinum, V. coriaceum and V- lutescens. Van Ittalie ascertained the presence of valerianic acid in Viburnum sambueinum. On this ground Hallier supposed the close relationship of Viburnum with the Valerianaceae (see Hallier in Med. Rijks-Herb. No. 14: 36. 1912; No. 37: 92. 1918).

DISTRIBUTION. — Moluccas (Buru) ; Philippines (Luzon, Negros). LOCAL NAME. — According to Merrill: taringongog (Neg.). The variability of Viburnum luzonicum has led to the distinction of several segregate taxa, viz. Viburnum sinuatum Merr., V. laxum Elmer, V. floribundum Merr., V. luzonicum var. apoense Elmer, and moreover a few species and varieties from Formosa. They are all based on the shape of the leaf and the density of the indument only. As Merrill already did in his Enumeration, I think Viburnum laxum differs too little from typical V. luzonicum to constitute a marked variety even. According to Elmer the leaves are more or less tapering at the base with the greatest width across the middle, not below the middle as in Cuming 1345, the specimen upon which Rolfe founded his Viburnum luzonicum. Viburnum floribundum is said to be distinguishable by its nearly glabrous leaves, which are less acuminate, more strongly toothed, rounded and inequilateral at the base, as well as by its dense inflorescence. Al- though the leaves of Ramos & Edaiio 38087 are indeed much more glabrous than in the type of Viburnum luzonicum, I cannot agree that the midrib is only slightly puberulent and the inflorescence strikingly dense. Inequilateral leaves occur in all forms of Viburnum luzonicum in the present sense. Viburnum sinuatum agrees almost completely with Viburnum flori- bundum, except for the shape of the leaves, which are long-acuminate and still-more strongly toothed. I could not find clear differences either in the flower or in the fruit. 164 R E I N W A R D T I A [VOL. 1 Viburnum luzonicum var. apoense on the contrary has narrower, hardly toothed leaves. Those of most of the specimens collected in Min- danao are rather striking. They are subcoriaceous; whereas in Viburnum, floribundum and in V. sinuatum the primary nerves are nearly straight and end in the teeth, those of the variety apoense from Mindanao are strongly curved upward near the margin and rather distinctly anasto- mosing, but this is completely due to the absence of the toothing of the leaves. Several specimens have both nerves reaching the margin and nerves distinctly anastomosing. The specimens collected in Luzon which are identified by Elmer as var. apoense, do indeed possess almost entire leaves, but they are not subcoriaceous and the nerves end in the small teeth. Though in doubt I have therefore referred them to this variety. On the other hand I might refer Ramos & Edaiio 38921, mentioned in the Enumeration under var. apoense, to var. sinuatum on account of the strongly toothed leaves. At the utmost I might regard 'apoense,' 'floribundum,' and 'sinuatum' as varieties, but they are far from being well marked and after deducting of these varieties the remaining specimens show still a great polymorph- ism. Some of them might just as well have been reduced to one of the varieties. As to how far the several forms of Viburnum formosanum distin- guished by Nakai arid the species of Hayata correspond with the above- mentioned varieties must await further investigation.

SPECIES WRONGLY RECORDED FOR THE AREA Viburnum zippelii Miq. .- . In his "Flora Indiae batavae" (2: 122. 1856) Miquel described a species of Viburnum under the name of V. zippelii. As locality he indicat- ed "Nieuw-Guinea? (Herb. Zippel)." The description was made after a fruiting specimen: "Plores non vidi. Affine videtur Vib. acuminato Wall, nee a V. sambucino longe distat, sed illius folia integerrima, hujus inflorescentia basi bifoliata, foliaque multo minus coriacea, nee punctata." The type is in the Rijksherbarium at Leiden (no. 899.69—594). Obviously Miquel compared his new species with V. acuminatum on account of the densely punctulate under side of the leaves, the resemblance apart from that not being great. Even slighter is the similarity to V. sambucinum. For a long time I was unable to place it among the other Malayan species of the genus and I was inclined to agree with Hallier who remarked, (in Med- Rijks-Herb. No. 14: 36. 1912), that it was a strongly character- ized species and for that reason possibly a representative of the genus in New Guinea, whence for the rest Viburnum is unknown. Possibly, for the accompanying label is not written in Zippelius's own hand, but it is a printed one and Blume already placed a ? after "Nieuw-Guinea." Zippe- lius participated in an expedition to the coasts of SW New Guinea in 1828. He died on the way back and his valuable collections have been worked out by others. Later on V. zippelii has never been collected in Malaysia (cf. also Scheffer in Ann. Jard. bot. Buitenz. 1: 28. 1876). I was much astonished when I accidentally came across a specimen of a Japanese Viburnum in Herbarium Bogoriense, collected as a species of Cornus by Em. Weiss (no. 50) near Nagasaki, Japan. The plant was 166 R E I N W A R D T I A [VOL. 1 identified in 1943 by Hatusima as V. japonicum (Thun'b.) Spr. and is evidently identical with Miquel's V. zippelii. Although I have no further specimens of V. japonicum at my disposal I am convinced that the deter- mination of Hatusima is right, in testing it with the description of Nakai {in J. Coll. Sci. Imp. Univ. Tokyo 42: (2) : 30. 1921) and others. The identity will be already evident from the comparison of Miquel's description with that of Nakai. The spotty glands at the base of the under side of the leaves, mentioned by Miquel, also occur in the examined specimen of T7. japonicum. Viburnum japonicum is only known from Kiusiu and Hondo and it is quite improbable, if not impossible, that Zippelius's plant originates from New Guinea. In my opinion it must be a Japanese specimen or it must have been gathered in the Bogor Botanic Gardens, whe#re Zippelius was employed since 1825 as Assistant Curator. It is very likely that the species was cultivated at Bogor, although I could not find it mentioned in the catalogues of the Gardens. In "Annales d'horticulture et de bota- nique" (2: 97. 1859), Van Hall described a " Viburnum m,acrophyllumi Thunb.," obviously belonging to V. japonicum, "recu par l'intermediaire de M. Teysman, le celebre jardinier en chef du jardin botanique de Buitenzorg." It is curious that Miquel in "Prolusio florae japonicae" {in Ann. Mus. Lugd. Bat. 2: 268. 1868) published this plant as V. buergeri Miq.! In reading the diagnosis of Cornus japonica in Thunberg's "Flora japonica" (63. 1784) one is struck by the following passages: "Filamenta 4 . . . Germen superum." Sprengel (Systema 1: 934. 1825) nevertheless referred it to Viburnum, whereas De Candolle (Prodr. 4: 273. 1830) still treated it as a "Cornus?" I ba"se the identity of Thunberg's Cornus japo- nica with the plant in question only on Maximowicz's assertion in "Me- langes biologiques" (10: 664. 1880): "Genus'ex sola descriptione optime enucleavit d. Sprengel." EXCLUDED SPECIES Viburnum alternifolium Zoll. & Mor. Viburnum alternifolium Zoll. & Mor., Syst. Verz. 59. 1845—1846 = Ilex alterni- folia (Zoll. et Mor.) Loesener in Nov. Acta Leop.

REINWARDTIA Published by Herbarium Bogoriense, Kebun Raya Indonesia Volume 1, Part 2, pp. 171-189 (1951) THE FERN-GENUS PLEOCNEMIA PRESL R. E. HOLTTUM* SUMMARY 1. The genus Pleocnemia Presl is redefined arid differentiated from Tectaria- Cav. and Arcypteris Underw., the latter genus being very closely related to Pleocne- mia. 2. The configuration of the perispore proved to be of importance for the characterisation of the .species. In this regard three types are distinguished, perispore forming1 crisped anastomosing wings, perispore consisting of many slender spines, and, an intermediate type, perispore forming many small separate wings. 3. Tentatively 15 species are recognized. Of these, Pleocnemia winitii Holttum, P. acuminata Holttum, P. pleiotricha Holttum, P. presliana Holttum, P. dimidiolobata Holttum, P. tripinnata Holttum, and P. seranensis Holttum are described as new, aa well as one variety, P. conjugata var. elatior Holttum. 4. The following new combinations are made: P. hemiteliiformis (Racib.) Holt- tum (basinym: Pleocnemia leuzeana var. hemiteliaeformis Racib.), P. olivacea (Copel.) Holttum (basinym: Tectaria olivacea Copel.), P. kingii (Copel.) Holttum (basinym: Tectaria kingii Copel.), and P. chrysotricha (Bak.) Holttum (basinym: Nephrodium chrysotrichum Bak.). 5. Reductions to synonymy are: Pleocnemia javanica Presl to P. conjugata (Bl.) Presl, and Dictyopteris compitalis v. A. v. R. to P. hemiteliiformis (Racib.) Holtt. This genus, as originally published in 1836, included only one species, Pleocnemia leuzeana, based on Polypodium leuzeanum Gaudichaud (1827), the type of which was collected in the Moluccas. Presl placed Pleocnemia among the Polypodioid ferns (without indusia), and his figure clearly shows a naked sorus. But when he examined Cuming's Philippine collec- tions, he found that some were indusiate, and in his "Epimeliae" (p. 50) he placed the genus next after Nephrodium, describing two more species. It is not however clear whether Piesl recognized that some species of Pleocnemia could be indusiate and some not. Fee, in his "Genera Filicum," speculated on this point. He remarked on the confusion in the labelling °f Cuming's specimens (specimens distributed under the same number not always agreeing together), but he evidently considered that indusiate and exindusiate specimens could represent the same species, though perhaps they did not grow on the same plant. *Professor of Botany, University of Malaya, Singapore. — 171 — Rein Vol 1, Part 2 pp 66 -220_Page_21 Rein Vol 1, Part 2 pp 66 -220_Page_22 Rein Vol 1, Part 2 pp 66 -220_Page_23 Rein Vol 1, Part 2 pp 66 -220_Page_24 Rein Vol 1, Part 2 pp 66 -220_Page_25 Rein Vol 1, Part 2 pp 66 -220_Page_26 Rein Vol 1, Part 2 pp 66 -220_Page_27 Rein Vol 1, Part 2 pp 66 -220_Page_28 Rein Vol 1, Part 2 pp 66 -220_Page_29 Rein Vol 1, Part 2 pp 66 -220_Page_30 Rein Vol 1, Part 2 pp 66 -220_Page_31 Rein Vol 1, Part 2 pp 66 -220_Page_32 Rein Vol 1, Part 2 pp 66 -220_Page_33 Rein Vol 1, Part 2 pp 66 -220_Page_34 Rein Vol 1, Part 2 pp 66 -220_Page_35 Rein Vol 1, Part 2 pp 66 -220_Page_36 Rein Vol 1, Part 2 pp 66 -220_Page_37 Rein Vol 1, Part 2 pp 66 -220_Page_38 Rein Vol 1, Part 2 pp 66 -220_Page_39 Rein Vol 1, Part 2 pp 66 -220_Page_40 Rein Vol 1, Part 2 pp 66 -220_Page_41 Rein Vol 1, Part 2 pp 66 -220_Page_42 Rein Vol 1, Part 2 pp 66 -220_Page_43 Rein Vol 1, Part 2 pp 66 -220_Page_44 Rein Vol 1, Part 2 pp 66 -220_Page_45 Rein Vol 1, Part 2 pp 66 -220_Page_46 Rein Vol 1, Part 2 pp 66 -220_Page_47 Rein Vol 1, Part 2 pp 66 -220_Page_48 Rein Vol 1, Part 2 pp 66 -220_Page_49 Rein Vol 1, Part 2 pp 66 -220_Page_50 Rein Vol 1, Part 2 pp 66 -220_Page_51 Rein Vol 1, Part 2 pp 66 -220_Page_52 Rein Vol 1, Part 2 pp 66 -220_Page_53
