<div type="description"><p>Slender clustering rattan 5-8 m long. Stems closely clustering by short suckers, to 8 mm diam. without sheaths, to 15 mm with sheaths. Internodes c. 20 cm in length. Leaf sheaths rather densely whitish-grey-green when young and fresh, drying dull brown, densely covered with greyish-white scurfy indumentum, and crowded partial whorls of easily detached dark brown almost blackish spiculae to 2 mm long borne on pale yellowish-green bulbous bases united into delicate ridges; larger non-spiculate spines apparently very rare, usually absent, and chocolate-coloured scales also absent; geniculus present, rather densely armed with partial whorls of spiculae, these c. 0.5-1 mm distant; ocrea 3-5 mm high, sparsely spiculate, tattering with age. Leaf to 1.5 m in all; petiole 12-20 cm long, rounded abaxially, flattened adaxially, with rather sparse scattered groups of spiculae and dense rigid prickles c. 3-4 mm high on all surfaces, those on the lower surface, larger and usually reflexed; grey-white indumentum sparse, usually absent; rachis very sparsely armed adaxially, abaxially with scattered spines, or reflexed grapnel hooks in 3's to 5's, these continuing along the cirrus where c. 1 cm distant; whole cirrus c. 30-55 cm long. Leaflets 4-6 on each side of the rachis in the mature leaf, the lowermost as large as or larger than the rest, alternate throughout the length of the rachis; the largest to 25 x 11 cm, usually smaller and narrower; upper leaflet margins praemorse with rather rounded and distant lobing, rather obtuse or sometimes long-acuminate, whole leaflet markedly plicate with up to 10-12 plications; leaflets dull green above, sparsely white indumentose below or just faintly discolorous, not densely white indumentose, with scattered pale brown pseudo- parenchymatous scales along ribs on the upper surface; transverse veinlets rather obscure. Young leaves flushed pink on emergence, quickly turning dull green. Staminate and pistillate inflorescences superficially similar, sessile, erect, 21-31 x 4-6.5 cm, relatively rather broad; base of inflorescence at point of insertion about 5 mm wide and 3 mm through. Prophyll pale pinky-green on first emergence, then drying pale cinnamon-brown, when young with very sparse caducous white indumentum, chocolate-coloured scales absent, slightly toothed on margins below, a few scattered spiculae sometimes present on the abaxial surface near the base; beak c. 2 cm long by c. 8 mm wide at the base, rather robust. Axis with up to 8 first-order branches to 8 cm long below, decreasing above; first-order bracts tightly sheathing, to 3 mm long in sheathing portion, with long triangular apiculus to 8 mm long, pale brown. Staminate flowers solitary, borne on an alveolus 0.75 mm diam.; calyx with shallowly triangular lobes c. 0.75 mm long; corolla c. 3 mm long split almost to the base into 3 lobes c. 3 mm x 1.25 mm near the base, tapering to a rather bluntly triangular tip; stamens 6, minutely epipetalous with filaments c. 1.25 mm long, bearing medifixed anthers c. 2 x 0.2 mm (only immature flowers available); pistillode minute. Pistillate flower unknown-but corolla persisting in fruit, with petals triangular c. 4 x 2.5 mm (in Beccari, described but without dimensions). Sterile staminate flower unknown to me (-in Beccari, described as 6 mm long). Fruit at maturity globose, c. 1.5 cm diam., tipped by the stigmatic remains and covered in 12 vertical rows of dark chestnut-brown scales with darker marginal lines; seed rounded, c. 1 cm diam., slightly depressed laterally, covered with a thin sarcotesta; endosperm with dark brown ruminations penetrating to 1.5 mm deep; embryo basal. Eophyll not known</p></div>
