Clustered moderate palm climbing to 50 m, more commonly 20-30 m. Stems ± circular in cross-section, without sheaths 10-15 mm in diameter, with to 25 mm; internodes 10-15 cm long. Leaf sheath longitudinally striate, sparsely to moderately armed with black caducous indumentum, particularly concentrated on the apex of the sheath; ocrea entire, somewhat saddle-shaped, with 1-1.5 cm rounded lobe adaxial to the leaf; knee narrow, linear, abrupt, up to 2.5 cm long. Leaves sessile, up to 1.5-2 m long; rachis up to 1 m long, abaxially rounded, adaxially flattened or slightly convex, becoming trapezoid then rounded in cross-section distally, with sparse to moderate black caducous indumentum below, armed along the margins with inequidistant reflexed, bulbous-based, black-tipped spines, becoming more sparsely armed distally; cirrus up to 1 m long, armed as the rachis proximally, becoming unarmed distally; leaflets up to 8-10 on each side of the rachis, obovate to trapeziform, narrowly contracted at the base, irregularly and broadly praemorse at apex, 7-16 cm long by 4-9 cm broad at the widest point, concolorous, somewhat coriaceous, with 8 or more main veins radiating from base, armed along the margins with stout forward and (rarely) reverse-facing angular spines, praemorse apex somewhat ciliate-spiny; lowermost leaflets smaller than the rest, erect or reflexed and laxly swept back across the sheath; acanthophylls up to 3.5 cm long, very fine, slender. Inflorescence with profuse, soft, velvety, papillose covering, up to 40 cm long, arching, rarely straight; peduncle up to 20 cm long; rachis 18-28 cm long, rachis bracts 1.5-2 cm, finely acuminate; rachillae distichous, 10-12 on each side, up to 10 cm long, decreasing distally, rarely straight, often arching, adnate to the inflorescence for 10 mm, decreasing distally. Flowers borne in close pairs, with less than 1 mm long incomplete bracts subtending each dyad; calyx 2-3 mm long by 4 mm wide at the mouth, with 3 distinct rounded lobes; corolla ± 1 cm long by 3 mm wide, divided to a third of its length; stamens united into 4 mm long epipetalous ring, free filaments less than 0.5 mm long; anthers less than 1 mm long; ovary 3 mm by 2 mm tipped with c.2 mm long style. Fruit at maturity, 1-seeded cylindrical to rhomboid, 2.5-3 cm long by 16-19 mm wide with 20-24 vertical rows of scales. Seed 2 cm long by 1.6-1.7 cm wide by 0.8 cm thick, flattened on one side with a shallow depression; embryo lateral, raised opposite flattened side.
