Borneopresent (World Checklist of Arecaceae)B
A very rare rattan known only from two collections - the type from West Kalimantan and one from G Gaharu in Serian District. (J. Dransfield, The Rattans of Sarawak. 1992)A

Discussion

  • It is similar to K. rostrata but can be distinguished immediately by the leaf which has a single pair of leaflets, rarely with an extra single leaflet on one side. (J. Dransfield, The Rattans of Sarawak. 1992)A

Biology And Ecology

  • K. furcata was found growing in a valley bottom in forest transitional between hill dipterocarp forest and kerangas at 350 m altitude on G Gaharu. (J. Dransfield, The Rattans of Sarawak. 1992)A

Etymology

  • Forked (J. Dransfield, The Rattans of Sarawak. 1992)A

Uses

  • The cane appears to be of good quality though very slender. (J. Dransfield, The Rattans of Sarawak. 1992)A
