Description

  • Clustering moderate rattan with stems to 30m branching in the canopy; stem without sheaths to 1.5 cm diam., with sheaths to 2.5 cm diam., internodes to 12 cm long. Sheaths bright green, with deciduous chocolate-coloured scales, sparse black spines to 2.5 cm and sparse black brittle spicules; ocrea very conspicuous to c. 25 × 5 cm, diverging from the stem at an acute angle, the two edges inrolled, armed with black spines to 2.5 cm, abundant black brittle spicules and deciduous chocolate-coloured scales; ants usually abundant and very noisy. Leaf to 1.5 m including cirrus to 75 cm and petiole to 20 cm; leaflets up to 7 on each side of the rachis, very shortly stalked, to 25 × 10 cm, bright green on upper surface, whitish beneath. Inflorescences produced from topmost 2-4 nodes, crowded but not forming a head; bracts densely covered in chocolatecoloured scales and black spicules; rachillae few, large, to 20 × 1.5 cm, with conspicuous bracts.
