Ceratolobus
Ceratolobus was a dioecious genus of flowering plants in the palm family found in Southeast Asia, commonly called rotan. Its species are now included within the genus Calamus.[1] They were only differentiated from Calamus and close relatives like Korthalsia by leaf sheath appendages or inflorescence variations.[2] The Greek genus name combines "horn" and "capsule".[3]
Description
When the genus Ceratolobus was distinguished from Calamus, its species were described as relatively delicate and vinelike smong rattans, very spiny and densely clustering, the stems eventually becoming bare and covered in leaf scars. The leaves, rachises, and petioles (when present) may be equipped with simple climbing adaptations like barbs, cirrus, and grapnel spines but the climbing habit mostly relies on stem spines, and their leaning, sprawling nature.
