What is "pogonotium"

Pogonotium is a dioecious genus of flowering plant in the palm family found in Malaysia and Borneo. Its close relatives are climbing rattans and while partially armed with climbing apparatus, its habit is sprawling and leaning but not effective climbing. The reduced inflorescence nestled between the auricles is unusual and distinguishes it from similar relatives like Calamus, Daemonorops and Ceratolobus. The name is Greek meaning "bearded".
