  • Clustering montane monoecious unarmed pinnate palm with stems rarely exceeding 2 m long. Stem to 2.5 cm diam. with internodes to 10 cm long, the stem surface densely covered with dark red-brown to blackish scales. Crownshaft only slightly swollen, to 70 cm long, 2.5 cm wide near the base. Leaf sheaths dull greenish-brown, densely covered with dark red-brown to blackish scales. Leaves about 6-8 in crown, to 1 m long in well-grown mature individuals, shorter in exposed individuals, occasionally up to 2 m long in rosette stages of juvenile; petiole to 40 x 0.5 cm, densely covered with silvery and dull reddish-brown scales; leaflets 7-12 on each side of the rachis, rather irregularly arranged and reflexed in the proximal part of the leaf, regular and opposite and divaricate in the distal part, with 1-2 folds; proximal leaflets longer than distal, 25-30 x 0.7-2 cm, the distal leaflets occasionally much smaller, the leaflets frequently constricted at the insertion on the rachis; bifid scales sometimes present on the main veins, on abaxial surface; abaxial surface of lamina also densely covered with minute scales and papillae. Inflorescence erect or pendulous, with spreading branches; peduncle to 2 cm long, 5 mm wide near the base; rachillae to 8 in number, 7.5 x 0.3 cm, somewhat flattened, glabrous, bearing distichously arranged flower groups up to 5 mm distant. Staminate flowers not known. Post anthesis pistillate flower with 3 imbricate, shortly apiculate, minutely ciliate, rounded sepals to 2 mm long; corolla with 3 petals similar to the sepals; ovary to 2 mm, oblong, tipped with an irregular, convoluted stigma. Rachillae turning reddish at fruit maturity. Mature fruit purplish-black, to 12 x 7 mm, tipped with the eroded stigmatic remains, with very thin pericarp with a poorly developed fibrous layer. Seed to 10 x 5 mm. Endosperm deeply ruminate. Embryo sub-basal. (Dransfield, J. 1980: Systematic Notes on Pinanga (Palmae) in Borneo)B
