Melocanna is a genus of tropical clumping bamboo (tribe Bambuseae of the family Poaceae). It comprises 3 species, found in East Asia. The genus is similar to Bambusa. The 48-year cycle of M. baccifera in northeastern India is responsible for the mautam phenomenon of bamboo flowering, followed by a plague of rats and famine.
This genus includes Beesha (Kunth). Species that were previously classified within this genus and are now excluded include:
- Melocanna humilis (Roepert ex Trinius), replaced by Bambusa humilis (Reichenbach ex Steudel)
- Melocanna virgata (Munro), replaced by Cephalostachyum virgatum (Munro Kurz)
- Melocanna zollingeri (Steudel) var. longispiculata (Kurz ex Munro), replaced by Schizostachyum blumei (Nees)
