<div type="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 &#215; 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 &#215; 12 mm, tipped with a beak to 2 mm and covered in 15 vertical rows of reddish-brown scales. Seed to 12 &#215; 8 &#215; 7 mm, deeply pitted; endosperm deeply ruminate. Seedling leaf pinnate with 6 very narrow leaflets held in a fan. (Fig. 68).</p></div>

<div type="uses"><p>Produces a coarse but durable cane of poor appearance, much used for the frameworks of carrying baskets.</p></div>

<div type="discussion"><p>This is one of the most widespread of Bornean rattans, occurring from sea level to 1,800 m altitude, and also one of the most variable.</p></div>
