Borneo present (World Checklist of Arecaceae)B
Sumatera present (World Checklist of Arecaceae)B
Recorded in Borneo only for East Kalimantan; elsewhere in Sumatra. (Dransfield, J. & Patel, M. 2005: Rattans of Borneo, an interactive key.)A


  • Near theratened. (Dransfield, J. & Patel, M. 2005: Rattans of Borneo, an interactive key.)A


  • Habit - Climbing; stems clustering; not branching in the forest canopy; not dying after flowering. Plants dioecious.
    Leaf-sheath - Tubular for most of its length; stem and sheath together 0.8-1 cm; flagellum absent; knee absent, or present; with spines similar to the rest of the sheath. Sheath surface lacking small horizontal ridges; without hairs or minute spines; green; scales on surface lacking. Leaf sheath with abundant spines; spines persistent; downward pointing, or upward pointing; of more or less the same size; the larger spines needle-like; the longest, excluding those at the mouth of the sheath 5-8cm. Spines straight; in life black; with smooth margins; the bases not swollen or crescent-like. Spines mostly grouped; where grouped together arranged in whorls; the whorls interlocking. Spines around the leaf sheath mouth scarcely different from those 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; 1 to 10 on each side of rachis, or 11 to 39 on each side of rachis; irregularly spaced and parallel; held in a single plane; linear-lanceolate; the leaflet tip acuminate. Longest leaflet 27-33 cm; not exceeding 2cm wide; with bristles on both faces; the margins with many bristles. Bristles not interlocking; short, dark or dark-tipped up to 5mm long. Leaflets conspicuously plicate; the veins not radiating; midrib raised and prominent adaxially. 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, or completely or partly pressed against the subtending branch. Flowers arranged in two rows. Male rachillae not less than 1 cm long. Female rachillae not congested; with conspicuously stalked flower cups. Bracts on the rachillae not net-like.
    Fruit - Globose; red resin (Dragon's blood) absent; one seeded. Calyx in fruit split part way and partly tubular. Fruit scales with a conspicuous central groove; the tips not recurved; when dry mid brown (excluding dark margins). Seed globose; the surface smooth.

  • This is a slender species of some economic importance. It is distinct in the numerous very slender black spines on the leaf sheaths and the irregularly arranged leaflets. (Dransfield, J. & Patel, M. 2005: Rattans of Borneo, an interactive key.)A
