Discussion

  • This species is one of the most conspicuous rattans of montane forest in the headwaters of the Temburong River at altitudes of 1,200-1,800 m above sea level. It is variable, some forms being very slender. It is closely related to D. korthalsii and other members of the complex of D. hystrix. (J. Dransfield, The Rattans of Brunei Darussalam. 1997)A
