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 grandis Griff.[

Daemonorops grandis is an evergreen, climbing palm, producing a cluster of unbranched stems that can be 20 metres long, but is often shorter. The stems climb into surrounding trees in the forest[
The plant is harvested from the wild as a local source of material for basket making and thatch.
Southeast Asia - Peninsula Thailand to Malaysia.
Ridges and lower slopes of hill dipterocarp forests[
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 for thatch[
The outer layer of the petiole and rachis are peeled and split into strips for making baskets and winnowing trays[
]. The stem is about 30mm in diameter without the leaf-sheaths; and up to 50mm in diameter with the sheaths[
