Borneopresent (World Checklist of Arecaceae)B
A local rattan found scattered in Brunei at altitudes up to 550 m above sea level. Elsewhere widespread throughout the northern part of Borneo. (J. Dransfield, The Rattans of Brunei Darussalam. 1997)A

Discussion

  • It is distinctive when fertile, but is much more difficult to determine when sterile. For differences between this species and closely related K. rostrata, see under the latter. (J. Dransfield, The Rattans of Brunei Darussalam. 1997)A

Biology And Ecology

  • K. furtadoana occurs sporadically in lowland forest. (J. Dransfield, The Rattans of Brunei Darussalam. 1997)A

Etymology

  • C.X. Furtado, important palm botanist at Singapore Botanic Gardens, active 1930-1960 (J. Dransfield, The Rattans of Brunei Darussalam. 1997)A

Uses

  • Not specifically recorded but it has a durable slender cane. (J. Dransfield, The Rattans of Brunei Darussalam. 1997)A
