Scattered throughout the lowlands of Sabah; elsewhere throughout endemic. (J. Dransfield, The Rattans of Sabah. Sabah Forest Records 13.. 1984)A

Discussion

  • D. elongata is found in lowland Dipterocarp forest, usually on hill-slopes. D. elongata is usually separable on the basis of the irregularly arranged leaflets, the short stature, the long petiole spines and the usually rounded fruit. (J. Dransfield, The Rattans of Sabah. Sabah Forest Records 13.. 1984)A

Etymology

  • Elongate, probably referring to the peduncle (J. Dransfield, The Rattans of Sabah. Sabah Forest Records 13.. 1984)A

Uses

  • None known. (J. Dransfield, The Rattans of Sabah. Sabah Forest Records 13.. 1984)A

Description

  • Moderate clustering rather short-stemmed rattan with stems rarely exceeding 4 m; stem without sheaths c 1 cm diam., with sheaths to 2 cm diam.; internodes rarely exceeding 6 cm. Leaf sheaths dark green rather densely covered with chocolate-coloured indumentum and armed with abundant scattered or partially whorled black reflexed or erect spines to 30 mm, usually much less, with pale bases; spines around leaf sheath mouth erect papery to 12 cm. Knee poorly developed. Leaf to 1.2 m, usually with a short cirrus to 30 cm with only a vestige, petiole to 40 cm, armed with distant, regular, large later to 5 cm, sometimes much shorter, and scattered shorter spines along the mid line of the abaxial surface; leaflets up to c 20 on each side of the rachis, regularly arranged below, irregularly arranged above; largest leaflets to 40 x 2 cm, armed with 3 rows of bristles on the upper surface, one row beneath, and along margins. Inflorescences male and female superficially similar, with rusty tomentose axes in very short stemme individuals with a long stalk to 30 cm, in climbing individuals with a much shorter stalk; all bracts quickly falling except for the first which may persist, to c 12 x 3 cm, brown, armed with distant groups of spines; male rachillae to 1 cm, female rachillae to 5 cm. Mature fruit relatively small, usually ± globose, up to 10 mm diam., covered in 15-19 vertical rows of straw-coloured scales (green when immature); seed globose, c 6 mm diam.; endosperm deeply ruminate.
