Known only from Kerakit on P. Banggi; endemic. (J. Dransfield, The Rattans of Sabah. Sabah Forest Records 13.. 1984)A

Discussion

  • D. banggiensis grows in lowland forest developed on the soft reef limestone at the southern end of Banggi Is.; here it is abundant, and one of the very few species of rattan in this forest type. It is probably closely related to D. curranii of Palawan. Its robust size, and fierce armature distinguish it from other members of the complex of species related to D. hystrix. (J. Dransfield, The Rattans of Sabah. Sabah Forest Records 13.. 1984)A
