In Sarawak known from three collections from the Mulu National Park, 4th Division. Otherwise known only from the type from W Kalimantan. Endemic to Borneo. (Dransfield, J. 1992: The Rattans of Sarawak)A


  • This spectacular palm was collected in wet kerangas forest at c. 1 - 200 m elevation in the Mulu National Park. Beccari described the species from a single collection made by Hallier in W Kalimantan; the type material is incomplete and Beccari concluded that Halliefs plant was a robust climbing palm, even though no cirrus is present in the type. However, the Mulu collections match the type in every respect. D. spectabilis is easily distinguished from D. ingens by the paired leaflets and the very slender peduncle.
