"description"><p>Slender clustering rattan climbing to
3 m; stem without sheaths
4-
5 mm diam., with sheaths
8-
10 mm diam., internodes c.
8-
12 cm long. Sheaths dull dark green, drying brown, armed with scattered and partially whorled short triangular spines to
4 mm interspersed with very fine close, minutely spiny ridges encircling the sheath, grey indumentum abundant between the ridges; knee present but rather poorly developed; ocrea short, tattering, minutely ridged. Flagellum to
1 m or more. Leaf ecirrate, to c.
75 cm including the petiole to
13 cm; petiole armed with scattered reflexed and horizontal spines and a few ridges near the base; leaflets
9-
13 on each side of the rachis, rather distant but
± regularly arranged, the longest to c.
25 × 1.5 cm, the shortest at the leaf tip c.
14 × 1.2 cm, rather narrow, gradually narrowed to a long slender tip, minutely bristly on the lower surface. Inflorescences flagellate, to c.
2 m, with about
3 very distant partial inflorescences; prophyll very tightly sheathing, elongate, armed with short prickles and ridges; partial inflorescences to c.
30 cm long, very lax and slender, bearing distant rachillae, the male to c.
3 cm, the female to c.
5 cm, each with distant large flowers borne on large flower cushions. Mature fruit
