It has been proposed - William J.Baker; A revised delimitation of the rattan genus Calamus (Arecaceae), Phytotaxa 197 (2): 139-152; 2015 - that the genera Ceratolobus, Daemonorops, Pogonotium and Retispatha should all be subsumed into a revised and expanded concept of the genus Calamus. This revised treatment has been accepted in the 'World Checklist of Selected Plant Families' and is likely to recieve further acceptance. For the time being, until there is wider acceptance of this change, we are not moving these species across into Calamus. The new name for this species in Calamus will be Calamus elongatus (Blume) Miq.[

Daemonorops elongata is an evergreen, climbing palm, producing clusters of slender, unbranched stems, rarely more than 4 metres long, that scramble into the surrounding vegetation.
The plant is harvested from the wild as a local source of material for thatching.

Most species in this genus are more or less vigorous climbing plants in rainforests. In general, they are likely to grow best with their roots in the shade but with enough gap in the canopy to encourage their stems to grow up towards the light. They are also likely to grow best in a humus-rich soil[
A dioecious species, both male and female forms need to be grown if fruit and seed are required[
The leaves are used locally for thatching temporary shelters[
]. The leaves can be up to 150cm long on a petiole up to 50cm long[
