Endiandra can be recognized by thepaniculate inflorescence in which the ultimate cymeare not strictly oppposite, bisexual flowers with 3stamens (rarely 2 or 6) having 2 loculated ofanthers, producing fruits which are free onreceptacles. Endiandra was first described byRobert 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 woodanatomy (van der Werff & Richter, 1996).New Guinea is thought to be the main center ofdistribution of the genus, with a high number ofendemic species. During the preparation of ataxonomic treatment of Endiandra in New Guinea,several specimens with different characteristicscompared to other Endiandra species wererecognized. Detailed observation of the charactersin each specimen suggested that the specimensrepresent two undescribed species.341342 REINWARDTIA [VOL1. 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 aresimilar to E. oviformis Kosterm., but the latter hassmooth leaves, without prominent minor venation as inE. areolata. — Type: Indonesia, West Papua, Sorong,Remoe, 1 Sep 1948, Pleyte 733 (Holotype BO!; IsotypeL!, LAE).Tree up to 25 m tall, up to 20 cm in diameter.Twigs brown, solid, striate, glabrous. Terminal budsnarrowly elliptic, straight, 2-3 mm long, with denseappressed hairs. Leaves slightly clustered; petiolethin, slightly canaliculate, 1-1.2 cm long, glabrous;blade stiffly coriaceous, broadly elliptic, 9-11.4 x4.2-5.6 cm, glabrous, apex acute to obtuse, with ashort acumen of a few millimeters, base broadlycuneate to attenuate; midrib flat to slightly im-pressed above, raised below, glabrous; lateral veinsobscure, thread-like, slightly raised on both sur-faces, as prominent as minor veins; minor venationcoarsely 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; tepalsovate, ca. 0.6 mm long, pubescent outside, glabrousinside; stamens 3, each with a pair of glands at thebase; anthers somewhat rectangular, ca. 0.7 x 0.3mm, sessile, glabrous; locules small, nearlyrounded; 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 Indonesiai.e. Moluccas (Halmahera) and Papua (Sorong) andup to Idenburg River area (Jayawijaya Mountains).Habitat and Ecology.

Endiandra areolata is different from otherspecies of Endiandra in New Guinea because of insstiffly coriaceous leaves in which the lateral veinsare obscured by prominent areolate minor veinsand by its small, erect flowers. Coriaceous leavesare also found in E. oviformis Kosterm., but in thatspecies the dried leaves are pale and smooth.dark and prominently areolate, as in E. areolataAdditionally, E. areolata has somewhat rectangularanthers, which is an uncommon shape in Endian-dra, with a pair of small staminal glands at the baseof each stamen. Flowers of New Guinean species ofEndiandra 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 aroundthe base of the 3 stamens.The specimen label of Kostermans 1260 showsthe locality is Morotai, G. (Mount) Parapara. How-ever, Mt. Parapara is not in Morotai Island, insteadtwo localities are recorded as Parapara mountainlocation, i.e. Halmahera and Bacan Islands (http:www.traveljournals.net/explore/indonesia/locationsp/52.html). According to notes on Kostermans col-lecting localities, in 1949 he did an exploration inMoluccas especially in Morotai and Halmahera Is-lands but none was mentioned that he went furthersouth to Bacan Island (de Wilde & Baas 1995;http://www.nationaalherbarium.n1/fmcollectors/k/KostermansAJGH.htm). Therefore, we consider thatMt. Parapara that Kostermans went to was the onein Halmahera Island and we assume that Koster-mans may accidently put Morotai for G. Parapara.This is also the case with other specimens where heput Morotai for Tobelo, whereas Tobelo is actuallylocated in Halmahera Island.2. Endiandra lanata Arifiani, spec. nov. - Fig. 2,3.Endiandra lanata is recognized by dense curly hairson lower leaf surfaces, inflorescences, and flowers. Thespecies is almost similar to E. papuana Lauterb., but thelatter has more numerous flowers in its inflorescences,and bigger leaves. — Type: Papua New Guinea, Fergus-son Island, Milne Bay, Esa'ala, track between Tutubeaand Lake Lavu, 12 Nov 1976, Croft 68764 (HolotypeBO!; Isotype BO!, SING!, LAE).Tree up to 20 m tall, 50 cm in diameter.

Endiandra lanata is a species with fusedstaminal glands, unlike E. areolata that has separateglands. The species has inflorescences with verydense curly hairs similar to E. papuana Lauterb.,but E. lanata is distinct from E. papuana in bearingfewer flowers and having smaller leaves (7.5-13.5x 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 surfaceversus 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 twigsand 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-brownbark and flowers up to 8 mm.ACKNOWLEDGEMENTSThe first author would like to thank M. A.

Newly described species of Endiandra (Lauraceae) from New Guinea.

Two new species of Endiandra (Lauraceae), i.e. Endiandra areolata Arifiani and Endiandra lanata Arifiani are described from New Guinea. Both species have staminal glands, but their form is different in the two species.  Moreover, E. areolata Arifiani is characterized by its prominent areolation formed by the minor venation, and E. lanata Arifiani is easily recognized by the presence of a dense curly indument on its twig, leaves, inflorescences and flowers. </p
