Habitat and Distribution

Daemonorops periacantha is found in Borneo, Malaya, Sumatera. Widespread throughout
South Sumatra, Indonesia. Photo by Dr. John Dransfield, Royal Botanic Gardens, Kew/Palmweb.
Brunei. Elsewhere throughout Borneo, also in Sumatra and Johor. D. periacantha is found in lowland and hill dipterocarp forest up to c. 800 m above sea level, preferring the rather better soil types such as alluvial flats and valley sides rather than ridges. The abundant yellowish spines, generally robust habit and the grouped leaflets make this an easily recognised species. (J. Dransfield. 1997)/Palmweb.


Robust clustering rattan palm, with stems climbing to 10 m tall, rarely more, sometimes very short-stemmed; stem without sheaths 15-30 mm, with sheaths 30-80 mm in diam., internodes to 35 cm long, very rarely much shorter in short-stemmed forms. Sheath bright green, but very densely covered with bright yellow brown, black-tipped spines of varying length, the longest to 6 cm, pointing in several directions, and dense brown indumentum, spines around the sheath mouth upward pointing, to 8 cm long; knee usually prominent (absent in short-stemmed forms), armed as the sheath but spines reflexed. Leaflets to 45 on each side of the rachis, irregularly arranged in rather distant groups of 2-7, the longest leaflets to about 40 × 3 cm, bristly near the tip. Inflorescences to 1 m, including the peduncle to 50 cm, each bearing up to 10 partial inflorescences, each subtended by a leathery, bristly, brown hairy bract, falling at anthesis, the bracts to 30 × 4 cm; rachillae conspicuously brown tomentose. Mature fruit rounded or very slightly obpyriform, to 22 mm in diam., covered in 15 vertical rows of pale straw-coloured to pale brown pink-tinged scales. Seed rounded to 15 mm in diam.; endosperm deeply ruminate. Seedling leaf not known. (J. Dransfield. 1997)/Palmweb. Editing by edric.
