In lowland Pahang found in periodically inundated Peat Swamp Forest.


Slender clustering rattan 5-8 m long. Stems closely clustering by short suckers, to 8 mm in diam. without sheaths, to 15 mm with sheaths. Internodes about 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 about 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 about 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 about 1 cm distant; whole cirrus about 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.
