Description

  • Habit - Climbing; stems clustering; not branching in the forest canopy; not dying after flowering. Plants dioecious.
    Leaf-sheath - Stem and sheath together 1.35-1.65 cm; flagellum absent; knee absent. Sheath surface lacking small horizontal ridges; without hairs or minute spines; greenish-brown; scales on surface lacking. Leaf sheath with abundant spines; spines persistent; randomly orientated; of different sizes; the larger spines laminar; the longest, excluding those at the mouth of the sheath 1-3cm. Spines straight; in life black; with smooth margins; the bases not swollen or crescent-like. Spines mostly grouped; where grouped together irregularly arranged, or arranged in partial whorls or combs. Spines around the leaf sheath mouth much longer than on the rest of the sheath. Ocrea - Absent. Leaf-stalk - Present, usually greater than 3cm; armed; irregularly. Large well-defined auricles absent; blotches on petiole absent. Leaves - Cirrate; rachis armed; not hairy. Undersurface of newly emerged leaflets same as upper surface. Scales absent from leaflet surfaces. Leaflets sessile; 11 to 39 on each side of rachis; regularly spaced and parallel; held in a single plane; lanceolate; the leaflet tip acute. Longest leaflet 24.3-29.7 cm; not exceeding 2cm wide; with bristles abaxially only, (few or none above); the margins with no or very few bristles. Short, dark or dark-tipped up to 5mm long. Leaflets scarcely plicate; the veins not radiating; midrib not raised and prominent. Lowermost leaflets not reflexed across the stem. Apical leaflets not or scarcely joined; not less than 4 cm long.
    Inflorescence - Inflorescence axis erect along the axis, without clawed spines on the primary bracts; not rooting at its tip; much shorter than the leaves; the first bract not enclosing the inflorescences at anthesis. Partial inflorescence present; bracts at the base of the partial inflorescences split to the base and falling off before the flowers open. Rachilla lacking an enclosing bract; not at all pressed against the subtending bract. Flowers arranged in two rows. Female rachillae not congested; without conspicuously stalked flower cups. Bracts on the rachillae not net-like. (Dransfield J. and Patel M. 2005. Rattans of Borneo, an interactive key. Royal Botanic Gardens Kew.)A

Notes

  • A slender species with sheaths armed with large horizontal spines, regularly arranged leaflets and small inflorescences. (Dransfield J. and Patel M. 2005. Rattans of Borneo, an interactive key. Royal Botanic Gardens Kew.)A
