SHAW A. J. G. H. KOSTERMANS ABSTRACT Of the genus Caryodapknopaia 7 6pecie3 are known, of which two are described here for the first time. The genus ocenrs from Yunnan to Indochina, with the exception of C. tonkinensis, which goes as far as the Philippines and Borneo. Apparently most species are distributed by to Borneo during the glacial period, when a land connection existed. The genus is related to Nothaphoebe and Alseodaphne and hence belongs to Perseae.

Marga ini berkerabat dekat dengan Natkaphoebe dan Atseodapltne INTRODUCTION The small entirely Asiatic genus Caryodaphnopsis was created by Airy Shaw (Kew Ball. 1940), who thought, that it might belong to Apolloniea (it belongs to Perseae) and created the name because of similarities between its leaves and those of some species of Cryptocarya. Unluckily Caryodaphne ia another name for Cryptoearya, the genus ia not at all related to Cryptocarya and triplinerved leaves are found in practically all genera of Lauraceae. Superficially the leaves and their position are like those of many Cinnamomum species. The species C. tonkinertAis and baviensis had been originally described by Lecomte under Nothaphoebe, which was the correct disposition. In 1960 Shaw added C. laotica. W.F. Wang added in 1957 C.latifolia. In 1952 (J. sci. Research Indon. 1: 151) I had included Nothaphoebe, together with Alseodaphne and Caryodaphnopsis in the genus Persea, with which these genera are very closely related and hence it ia not 124 REIN WARD TIA [VOL. 9 amazing, that Elmer described Nothaphoebe tonkinensis from the Philippines as Persea pyriformis. There are, however, slight, but constant differences between Alseodaphne, Nothaphoebe and Caryodaphnopsis (Machihts has been referred definitely to Persea). All three have a fruit, attached to a naked pedicel (or when persistent or subpersistent, the tepals are not enlarged, as in Phoebe and Apollonias) They have unequal tepals, the outer three being much smaller, and large staminodeg (large is of course relative, they are large as compared to other Lauraceous genera). Alseodaphne differs from Persea by its swollen, fleshy fruit pedicel. Nothapkoebe, Caryodaphnopsis and Persea have an unaltered pedicel. The flower structure in the 3 genera is similar. Persea has long and slender filaments (also the staminodes), while Caryodaphnopsis and Nothaphoebe have short filaments (in Nothaphoebe sometimes lacking completely). The differences between Nothaphoebe and Caryodaphnopsis are: 1. The filaments are longer than in Nothaphoebe, but shorter than in Persea. 2. The anthers are relatively large in Caryodaphnopsis resembling those of Persea, Nothaphoebe has minute and depressed anthers, as in Alseodaphne. 3. The staminodes are hardly visible in Nothaphoebe, they are relatively large, sagittate, cordate in Caryodaphnopsis (as in Persea), but they are, contrarily to Persea very shortly stalked. 4. Caryodaphnopsis has opposite (or almost so) leaves, which is found neither in Persea, nor in Nothaphoebe or Alseodaphne 5. Most Nothaphoebe species have a whitish, cork-like fruit pedicel, Caryodaphnopsis has the fruit stalk of a Persea. It is pointed out here that complete references to the species are found in Kostermans, Bibliographia Lauracearum (1964); these are not repeated here. DISCUSSION ON MORPHOLOGICAL CHARACTERS B r a n c h e s . All species have slender, stiff branches, which are either cylindrical or quadrangular, as a rule both are found in the same species. The branchlets are usually thickened and laterally flattened at the nodes and if the branchlets initially are pilose, the pubescence persists on the nodes. In species with a pilose inflorescence and even KOSTERMANS: The genus Caryodapknops those with a glabrous one (the base is always pilose), the pubescence extends to the axillar area of the branchlets. L e a v e s . The leaves are always opposite or nearly so and perhaps also distichous. In all species the leaves arc chartaceous to thinly chartaceous and have a very uniform shape (subovate to elliptic) and texture. The upper surface is smooth, dull with usually impressed main nerves (or they are prominulous in a groove); the lower surface (in sicco) is yellowish brown (pale green in vivo). The leaves are always triplinerved, the basal veins vary in length from 1/2 to 2/4 the length of the leaf blade; accessory laterals number 2—3 pairs, are always arcuately ascendent. The only difference in the leaves is perhaps the leaf-size (but this is variable), the length and diameter of the petiole, but especially the prominence of the secondary, horizontal (scalariform) nerves. The tertiary nerves form in all species a lax, inconspicuous reticulation. The leaf apex ia always acuminate, the acumen being either broad and gradually tapered to a sharp point or slender. Both types occur in the same specimen. The very minute and sparse pilosity of the leaves is a distinctive characteristic. F l o w e r . The inflorescences are mostly axillary, sometimes axillary and terminal (C. laotica). They are thyrsoid, slender, the branches opposite, the terminal flowers in groups of 3 and more; ramifications and flowers are subtended by small, acute, ultimately deciduous bracts. Sometimes the axils of the branches bear short branches or single flowers. The panicles may be pyramidal, but in N. tonkinensis and metallica the lateral branches are very shortened and the flowers are in glomerules of heads. The flowers always have well developed, slender pedicels. The flowers itself look very much the flowers of some Annonaceae with the small, often scale like three outer petals and the large ovate-deltoid inner petals, initially coalescent in a pointed bud. The outside of the flower is either pilose or glabrous, the inside of the fleshy inner tepala is always densely pilose (in C. henryi more sparsely). The 6 fertile stamens are arranged in 3 whorls, the 4th whorl is staminodial, the staminodes being relatively large, ovate or ovate- sagittate or cordate, often with a thickened rim and with short filaments. The outer 2 whorls have large, flattened, oblong or rectangular anthers with 4 large introrse cells in pairs above each other (as in Persea), the inner are usually narrower with the lower cells extrorse, the upper lateral. All stamens have distinct filaments, which are about as long 126 R E I N W A R D T I A [VOL. 0 as the anthers. The outer filaments are concave and hence look smaller than the erect inner ones. The inner ones have two well-developed sessile glands an either side the filament base. In C. tonkinensis the anthers are more elongate and acuminate or apiculate and differ in this way considerably from the other species. The ovary is always glabrous, ellipsoid to ovoid-ellipsoid and merges into a slightly shorter style with very small, often lobed stigma. The flower receptacle is shallow. F r u i t . The fruit is large, soft, green or yellow-green, glossy, the mesocarp soft and pulpy (like avocado), the large seed covered by a thin, testa is at maturity separated from the endocarp by an air containing1 space. The fruit of most (or all) species are distributed by fresh water and hence the trees are found mostly along streamlets on alluvials. C. tonknensis in Borneo is also found farther away from the rivers and rivulets, because of the rising of the water during the rainy season followed by inundation of enormous areas. B o l e . The bole of C. tonknensis, the only species, which I could study in the field, has a smooth, redbrown bark and is partially or entirely fluted, the flutes merging- into numerous thin, hard not very conspicuous buttresses, which spread over the soil, typical for many tree species growing in similar habitats. The wood is pale yellowish, hard with a faint cigarbox wood smell; the heartwood is darker, very dense and not very thick. The tree flowers and fruits already at an early stage, when it is still ahrubtike and abundant and regular fruit setting accounts for its extensive distribution. Along streams the shrubs have often pendulous branches, similar to other rheophytes. KEY TO THE SPECIES aves pubescent uni! Plowers glabrous. Inner tepale 2 - 2 . 5 2. Flowers pubescent.

There are some slight differences with Lecomte's description. No difference exists between the position of the basal nerves in C. baviensis and tonkinensis. The petioles in C. baviensis are sometimes glabrescent, The length of the panicles varies in both species; considerably. The staminodes are either obtuse or sagittate. Although C. baviensis has the same kind of narrow panicle as G. tonkinensis, it may be easily differestiated by the smaller, glabrous flowers. Furthermore the leaf pubescence and the conspicuous scalariform secondary nerves on the lower leaf surface distinguish the two species. TONKIN, between Hoa Binb and Vu Ban, Prov.

Branches short to very short (flowers sometimes attached directly to the main peduncle). Pedicels up to 1 cm long, densely pilose. Flowers very densely pubescent. Outer tepals 1 mm long, inner ones ovate, This species, which I had the opportunity to observe in the field many times, occurs in Borneo on alluvial along streams and rivulets or in areas which are periodically inundated. The floating rather light fruit look somewhat like an avocado, but the pulp is thin and rather bitter and the seed much lighter. The tree starts already flowering and fruiting when it is small. It produces fruit regularly, hence its wide distribution. The sharp well- developed, but short buttresses it has in common with several other species, growing along rivers. Wang's specimen (W.S. Lion 175), as described in Aeta phytotax. Sinica, differs from C. tonkinensis by its coriaceous leaves and the description of the fruit does not fit either (mesocarpio dissoluto et reriucto, endocarpio cartilagineo). Without access to this specimen, it is impossible to ascertain its identity. The species could have easily spread from the mainland to Borneo during the glacial period, when a land connection and connecting river systems exsisted. TONKIN. Prov. Sontay, Mt.

Wa IB Reinwardtis B: 2R3, 1962; Bibl Laur. 211. 1961. - Typu oil Prov. Yunnan 801 (LE, isotypus). Exped. Sino - Ros Tree 15 m high, 30 cm diam. Branchlets subglabrous, quadrangular. Leaves chartaceous, glabrous, alternate and subopuosite, elliptic to rotundate-elliptic, 10 x 20—16.5 x 28 cm, rarely oblong, 8—11 x 25—30 cm, shortly acuminate, base cuneate, secondary nerves not conspicuous 74] KOSTERMANS: The genus Caryodaphttopsis 137 on the lower leaf surface. Petiole 2—3 cm long, sub-glabrous. Panicles terminal and axillary, 14—25 cm long, lax with widely spaced, short branchlets, patently, minutely pilosa. Pedicels 2—5 mm long, laxly pubescent. Tepals outside pubescent, inside fulvous-tomentellous, outer ones 1.2 mm long, inner ones 1.7—2.5 mm long, at base 2—2.5 mm wide, outer 6 stamens 1.8 mm long, inner ones 1.2 mm long; all filaments pilose, staminodes stipitate, sagittate, 0.75—1.1 mm long, outside pilose. Fruit ellipsoid, 2.9 x 4,3 cm. Pericarp 2 mm thick, hard, exocarp hard, 0.5 mm thick, mesocarp lacunair, 1 mm thick, endocarp consisting of lax fibres, 0.5 mm thick. Wang compares this species with 0. tonkinensis, to which, it is certainly related. As I had no access to the type specimen, I have copied and modified his description, combining it with characters gleaned from the plate. Nothing is said of the prominence of the secondary, horizontal veins, in the picture they are not very clear. The panicle is indeed similar to that of C. toTikinensis. The flowers seem to be smaller. The length of the leaf certainly exceeds that of C. tonMnensis, but this is variable character. YUNNAN. Chin-ping, Tau-Men-Shan, alt. ROD m, April, flow no-Ross. ad Prov.
