INTRODUCTION The genus Endiandra R.Br. is a genus within the laurel family (Lauraceae) which consists of over 100 tree species distributed from South China across the Malesian region to Australia and several Western Pacific Islands (Rohwer, 1993; van der Werff, 2001). Endiandra can be recognized by the paniculate inflorescence in which the ultimate cyme are not strictly oppposite, bisexual flowers with 3 stamens (rarely 2 or 6) having 2 loculated of anthers, producing fruits which are free on receptacles. Endiandra was first described by Robert Brown (1810) and is currently grouped to- gether with the genera Beilschmiedia, Potameia, Cryptocarya and Triadodaphne in the tribe Crypto- caryeae based on the inflorescence type and wood anatomy (van der Werff & Richter, 1996). New Guinea is thought to be the main center of distribution of the genus, with a high number of endemic species. During the preparation of a taxonomic treatment of Endiandra in New Guinea, several specimens with different characteristics compared to other Endiandra species were recognized. Detailed observation of the characters in each specimen suggested that the specimens represent two undescribed species. 341 342 REINWARDTIA [VOL 1. Endiandra areolata Arifiani, spec. nov. - Fig. 1, 3. Endiandra areolata is recognized by stiffly cori- aceous leaves with prominently areolate minor venation, and by erect flowers. The stiffly coriaceous leaves are similar to E. oviformis Kosterm., but the latter has smooth leaves, without prominent minor venation as in E. areolata. — Type: Indonesia, West Papua, Sorong, Remoe, 1 Sep 1948, Pleyte 733 (Holotype BO!; Isotype L!, LAE). Tree up to 25 m tall, up to 20 cm in diameter. Twigs brown, solid, striate, glabrous. Terminal buds narrowly elliptic, straight, 2-3 mm long, with dense appressed hairs. Leaves slightly clustered; petiole thin, slightly canaliculate, 1-1.2 cm long, glabrous; blade stiffly coriaceous, broadly elliptic, 9-11.4 x 4.2-5.6 cm, glabrous, apex acute to obtuse, with a short acumen of a few millimeters, base broadly cuneate to attenuate; midrib flat to slightly im- pressed above, raised below, glabrous; lateral veins obscure, thread-like, slightly raised on both sur- faces, as prominent as minor veins; minor venation coarsely areolate, prominent. Inflorescences panicu- late, axillary or terminal, ca. 5 cm long, with nu- merous flowers, sparsely pubescent, glabrescent; bracts caducous; pedicel slender, 0.5-1 mm long, pubescent. Flowers light brown (fresh), very small, erect, ca. 1.5 mm in diameter, pubescent; tepals ovate, ca. 0.6 mm long, pubescent outside, glabrous inside; stamens 3, each with a pair of glands at the base; anthers somewhat rectangular, ca. 0.7 x 0.3 mm, sessile, glabrous; locules small, nearly rounded; staminodes none; receptacles shallow, gla- brous inside; ovary ovoid, 0.6-0.7 mm long, gla- brous; style 0.5 mm long, stigma unconspicous. Fruits unknown. Distribution. The species is known from Indonesia i.e. Moluccas (Halmahera) and Papua (Sorong) and up to Idenburg River area (Jayawijaya Mountains). Habitat and Ecology. Secondary rain forest or swamp forest on clay, rocky subsoil. Etymology. Named after its prominent areolate ve- nation. Additional specimens examined. Indonesia, Papua, 4 km SW of Bernhard Camp, Idenburg River, 1 Mar 1939, Brass & Versteegh 13142 (BO, L); Moluccas, Morotai, Mt. Parapara, 28 May 1949, Kostermans 1260 (BO, L). Notes. Endiandra areolata is different from other species of Endiandra in New Guinea because of ins stiffly coriaceous leaves in which the lateral veins are obscured by prominent areolate minor veins and by its small, erect flowers. Coriaceous leaves are also found in E. oviformis Kosterm., but in that species the dried leaves are pale and smooth. dark and prominently areolate, as in E. areolata Additionally, E. areolata has somewhat rectangular anthers, which is an uncommon shape in Endian- dra, with a pair of small staminal glands at the base of each stamen. Flowers of New Guinean species of Endiandra vary in the presence and absence of sta- minal glands. When present, the glands can be sepa- rate, with a pair of glands at the base of each sta- men, or fused to form a disc-like structure around the base of the 3 stamens. The specimen label of Kostermans 1260 shows the locality is Morotai, G. (Mount) Parapara. How- ever, Mt. Parapara is not in Morotai Island, instead two localities are recorded as Parapara mountain location, i.e. Halmahera and Bacan Islands (http: www.traveljournals.net/explore/indonesia/locations p/52.html). According to notes on Kostermans col- lecting localities, in 1949 he did an exploration in Moluccas especially in Morotai and Halmahera Is- lands but none was mentioned that he went further south to Bacan Island (de Wilde & Baas 1995; http://www.nationaalherbarium.n1/fmcollectors/k/ KostermansAJGH.htm). Therefore, we consider that Mt. Parapara that Kostermans went to was the one in Halmahera Island and we assume that Koster- mans may accidently put Morotai for G. Parapara. This is also the case with other specimens where he put Morotai for Tobelo, whereas Tobelo is actually located in Halmahera Island. 2. Endiandra lanata Arifiani, spec. nov. - Fig. 2, 3. Endiandra lanata is recognized by dense curly hairs on lower leaf surfaces, inflorescences, and flowers. The species is almost similar to E. papuana Lauterb., but the latter has more numerous flowers in its inflorescences, and bigger leaves. — Type: Papua New Guinea, Fergus- son Island, Milne Bay, Esa'ala, track between Tutubea and Lake Lavu, 12 Nov 1976, Croft 68764 (Holotype BO!; Isotype BO!, SING!, LAE). Tree up to 20 m tall, 50 cm in diameter. Twigs solid, dark brown, with dense curly hairs, sparser on older twigs. Terminal buds conical, 3-5 mm long, with dense curly hairs. Leaves alternate; petiole thin, terete, 0.8-1.5 cm long, flat above, curly pu- bescent; blade chartaceous, elliptic or subobovate, 7.5-13.5 x 4-6.5 cm, glabrous above, with curly 3)12] ARIFIANI et al.: Newly described species of Endiandra (Lauraceae) from New Guinea 343 hairs. whitish or glaucous below, apex acute to ob- tuse, with a small acumen, base cuneate to attenu- ate: midrib slightly impressed above, with sparse curly hairs, raised below, with dense curly hairs; lateral veins 5-7 pairs, slightly impressed or flat, with sparse curly hairs above, raised with dense curly hairs below; minor venation finely reticulate. Inflorescences paniculate, length up to 17 cm or more, axillary or subterminal, fewer-numerous flowered, rusty brown, densely curly pubescent; bracts linear or lanceolate, 1-2 mm long; pedicels slender, 2.5-3 mm long, with dense curly hairs. Flowers yellow (fresh), spreading, up to 8 mm in diameter; tepals subequal, the inner ones smaller, ovate or broadly ovate, 2.2-2.5 x 1.5-2.5 mm, gla- brous inside, with dense curly hairs outside; glands united to form a disc-like structure; stamens 3; an- thers ovate, protruding from the fused glands, gla- brous; locules roundish, small; staminodia none; receptacle deep, pubescent inside; ovary ellipsoid, 0.5 mm long, glabrous; style short; stigma incon- spicuous. Fruits unknown. Distribution. The species found in Papua New Guinea, in the districts of Morobe, Gulf and Milne Bay. Habitat & Ecology. Lowland rain forest to lower montane forest, alt. 150-823 m. Etymology. Named after its dense curly indument (woolly = lanatus). Local name. Kovitiomatanga (Middle Waria). Additonal specimen examined. Papua New Guinea, Gulf District, near Putei, junction of Tauri and Kapau Rivers, 9 Mar 1966, Craven & Schodde LAE947 (BO, L); Morobe District, Titapuba, 1 Oct 1966, Streimann & Kairo NGF26160 (BO, LAE). Notes. Endiandra lanata is a species with fused staminal glands, unlike E. areolata that has separate glands. The species has inflorescences with very dense curly hairs similar to E. papuana Lauterb., but E. lanata is distinct from E. papuana in bearing fewer flowers and having smaller leaves (7.5-13.5 x 4-6.5 cm in E. lanata vs. 10-19 x 7-10 cm in E. papuana). Additionally, the minor leaf veins of E. lanata are fine and prominent on the upper surface versus obscure and smooth in E. papuana. Endian- dra lanata also shows affinity to E. gemopsis Kos- term., but the former has more hairs on the twigs and inflorescences compared to E. gemopsis. Addi- tionally, E. gemopsis has pale bark and small flow- ers (1.5-2 mm), whereas E. lanata has dark-brown bark and flowers up to 8 mm. ACKNOWLEDGEMENTS The first author would like to thank M. A.
