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 calicarpus Griff.[

Daemonorops calicarpa is an erect, clustering, thicket-forming, almost stemless, non-climbing evergreen palm[
]. The leaves are about 2 metres long, with a long petiole[
The plant is harvested from the wild as a local source of material for thatching and basketry.

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[
The plant is monocarpic, living for a number of years without flowering, but them flowering freely and dying afterwards[
A dioecious species, both male and female forms need to be grown if fruit and seed are required.
The leaves are used for thatching[
The outer part of the leaf stem is stripped for weaving baskets[
