Habitat and Distribution

Daemonorops oxycarpa is endemic to Borneo. Widespread throughout Brunei. Elsewhere in
Kuala Belalong, Brunei Darussalam. Photo by Dr. William J. Baker, Royal Botanic Gardens, Kew/Palmweb.
Sarawak, Sabah and W Kalimantan. D. oxycarpa is commonly found in the lowlands at altitudes up to about 900 m above sea level; it seems to be quite tolerant of disturbance and is particularly abundant on alluvial soils. It has also been collected in kerangas. (J. Dransfield. 1997)/Palmweb.

Description

Moderate clustering climbing rattan palm, to 15 m; stem without sheaths to 20 mm in diam., with sheaths to 30 mm in diam., internodes rarely more than 10 cm long. Sheaths dull green but almost completelycovered in thick purplish-brown indumentum and sparse groups of flat papery, laciniate, hairy-margined dull brown spines to 2 cm, the groups often arranged in partial whorls; knee very conspicuous, narrow and swollen, but scarcely wrinkled; ocrea inconspicuous. Leaf cirrate to 3 m including cirrus to 1.2 m and petiole to 40 cm; petiole margins armed with a regular row of conspicuous long rigid golden-yellow spines to 7 cm; leaflets regularly arranged, about 60 on each side of the rachis, 2-3 cm distant, the longest to 27 × 1.5 cm, rather limp, the upper surface with up to 5 rows of bristles, the margins bristly, but the lower surface with only the main vein bristly. Inflorescence pendulous, to 50 cm, with primary bracts dull brown tomentose, armed with papery spines, the whole bracts quickly falling at anthesis; partial inflorescences about 6, rather lax, to 15 cm. Mature fruit ovoid, sometimes rather sharply pointed, to about 1.5 × 1 cm, rarely more, covered in 16 vertical rows of pale brown to chestnut-brown, rather convex scales. Seed ovoid to oblong, to 12 × 7 mm; sarcotesta sweet; endosperm deeply ruminate. Seedling leaf not known. (J. Dransfield. 1997)/Palmweb. Editing by edric.

The armature and coloration of the sheaths of this species are so characteristic that it should easily be identified. The strange bulbous, scarcely wrinkled knee, the purplish brown colour, the papery, grouped spines and the golden-yellow petiole spines are diagnostic. Beccari described the fruit as being rather narrow and pointed, and indeed the type specimen has such fruit; other populations from the 1st Division also have pointed fruit while those from eastern Sarawak and Sabah have ovoid fruit.
