Borneopresent (World Checklist of Arecaceae)B
A very rare palm known only from G Gaharu on the border with Kalimantan in the 1st Division; endemic. (J. Dransfield, The Rattans of Sarawak. 1992)A

Discussion

  • P. moorei is so far known only from a few individuals observed near the summit of G Gaharu at c. 600m altitude; it grows in very mossy, submontane kerangas forest on sandstone. It is very inconspicuous and could be passed over as a seedling of a species of Calamus or Daemonorops. From the other two species of Pogonotium it is immediately distinguishable by the very few leaflets and the top-shaped fruit. (J. Dransfield, The Rattans of Sarawak. 1992)A

Etymology

  • H. E. Moore Jr., 1917 - 1980, eminent palm botanist (J. Dransfield, The Rattans of Sarawak. 1992)A

Uses

  • Not known (J. Dransfield, The Rattans of Sarawak. 1992)A

Description

  • Solitary, low, short-stemmed erect rattan, not exceeding 2 m tall. Stem without sheaths c. 10 mm diam., with sheaths c. 18 mm diam., internodes c. 5 cm long. Sheaths armed with abundant, close, oblique and horizontal combs of black or straw-coloured spines, 1-22 mm long and abundant pale brown tomentum; ear-like processes c. 8.5 x 1.5 cm, gradually tapering, convex, armed as the sheath on the outer surface, the inner surface unarmed.

Inflorescence, only female known, very small and inconspicuous, held erect between the auricles; peduncle very short or absent, the prophyll c. 12 cm long, split opposite the leaf sheath (?always), hairy and bearing abundant spines and spicules as the sheath; other bracts small. Flowers small, glabrous. Mature fruit obpyriform, c. 13 x 9 mm, tipped with a short beak and covered in 15 - 16 vertical rows of pinkish-brown, scarcely channelled scales.
