"description"><p>Solitary, rarely clustering, moderate to robust rattan climbing to
15 m or more, but frequently flowering when only
3-
4 m tall; stem without sheaths to
18 mm diam., with sheaths to
20-
35 mm diam., internodes generally rather short, not usually more than
10 cm. Sheaths dull dark green, densely armed with scattered triangular flattened black spines,
3-
40 mm (in montane forms spines around the leaf sheath mouth crowded, erect, very long, to
140 mm), black indumentum abundant between the spines; knee grossly swollen; ocrea membranous, to
7 mm, usually obscured by spines. Flagellum to
5 m, heavily armed with reflexed spines. Leaf ecirrate, distinctly curved, to c.
1.5 m including the petiole to
35 cm; petiole strongly channelled on upper surface, armed with regular groups of spines
5-
20 mm along the margins, and a central row of spines to
20 mm on the lower surface; leaflets
40-
60 on each side of the rachis, curved, very regular, c.
3 cm apart, the longest to
35 × 1.5 cm, leaflet margins slightly but distinctly thickened, unarmed on the upper surface, lower surface with
3-
5 main veins armed with close very short bristles, transverse veinlets conspicuous. Inflorescence flagellate, very long, to
5 m or more, bearing up to
5 very distant pendulous partial inflorescences, to
1 m or more long, in male partial inflorescences branching twice to give short dark brown rachillae to
2 cm, bearing dense distichous flowers, in female branching once to give rachillae c.
20 cm long, bearing lax distichous flowers. Mature fruit ovoid, c.
16 × 12 mm, tipped with a beak to
2 mm and covered in
15 vertical rows of reddish-brown scales. Seed to
12 × 8 × 7 mm, deeply pitted; endosperm deeply ruminate. Seedling leaf pinnate with
