Rhipidocladum

About

Rhipidocladum is a genus of New World woody bamboo in the grass family. It is found in Mesoamerica, Trinidad, and South America. The genus is characterized by having erect, non-pseudopetiolate culm leaves, numerous branchlets arising in an aspidate (fan-like) array, and by having true caryopses as fruit. The name is derived from the Greek rhipid meaning "fanlike" and clad meaning "branch".
