records from Kalimantan, abundant in Sabah and Sarawak. D. sparsiflora is a common rattan usually found associated with richer soils in primary and disturbed forest, in valley bottoms, lower hill slopes and riverside alluvium at altitudes up to about 1000 m above sea level.

Description

Slender to moderately robust clustering rattan palm, with stems to 20 m, frequently flowering when much less; stem without sheaths 8-18 mm in diam., with sheaths to 27 mm in diam., internodes to about 20 cm long. Sheaths dull to bright green, armed with scattered rather broad-based, triangular yellowish-brown or green spines, rarely exceeding 15 mm, and brown indumentum; knee conspicuous. Leaf cirrate to about 2 m including petiole to 20 cm and cirrus to 80 cm; leaflets about 50 on each side of the rachis, stiff, to 25 × 1 cm, usually very close and regular, parallel-sided, abruptly and neatly narrowed at the base and acuminate in drip-tips to 2 cm long, upper surface with main rib bristly and a row of bristles on each side, margins bristly, lower leaflet surface sparsely to densely covered with minute brown scales and only mid rib bristly. Inflorescences bright reddish-brown at anthesis, arching away from the stem to 40 cm only, primary bracts soon falling, other bracts very inconspicuous; flowers borne on distinct short stalks; first order branches about 6, each to about 12 cm, crowded, covered with brown indumentum. Mature fruit rounded (immature occasionally ovoid), rarely exceeding 1 cm in diam., covered in 14-16 vertical rows of dull brown scales. Seed ± rounded, about 6 mm in diam.; sarcotesta sweet, thin; endosperm deeply ruminate. Seedling leaf pinnate with about 6 leaflets on each side of the rachis, very neatly and stiffly held. (J. Dransfield. 1997)/Palmweb. Editing by edric.

It is an unmistakable rattan with its very neat leaflets and sparsely spiny sheaths; the sudden and neat contraction of the leaflets is highly diagnostic. Seedlings are exquisite and would make fine ornamentals; but for the sparseness of fine bristles they could be confused with seedlings of rattans related to Calamus hispidulus. (J. Dransfield. 1997)/Palmweb.
