  • Robust clustering and branching rattan with stems climbing to 40 m or more, confined to peat swamp forest. Stems without sheaths to 2.5 cm diam. or more, with sheaths to 4 cm or more, internodes to 30 cm, longer in juveniles. Sheath ± unarmed, dull reddish-brown, covered in caducous black scales and pale brown hairs; ocrea tightly sheathing, unarmed, covered in scales and indumentum as the sheaths, tending to split opposite the petiole. Mature leaf to 2.5 m including the cirrus to 1 m and petiole to 15 cm. Leaflets 8-20 on each side of the rachis, borne on long stalks, narrow, to 30 × 4.5 cm, dark bluish-green on the upper surface, brownish on the undersurface, with frequent bands of deciduous chocolate-coloured scales. Inflorescences to 75 cm, highly branched; rachillae numerous, to 12 × 0.7 cm, dull brown tomentose. Fruit to 20 × 12 mm, covered in 19-21 vertical rows of straw-coloured scales. Seed 12 × 9 mm; endosperm deeply ruminate. Seedling leaf entire; juvenile leaves often very large and entire with blades reaching 100 × 30 cm. (Fig. 4, Pl. 1A). (J.
