Bambusa is a large genus of clumping bamboos.

Most species of Bambusa are rather large, with numerous branches emerging from the nodes, and one or two much larger than the rest. The branches can be as long as 11 m (35 ft). They are native to Southeast Asia, China, ******, the Himalayas, New Guinea, Melanesia, and the Northern Territory of Australia. They are also reportedly naturalized in other regions, e.g. Africa, Latin America, and various oceanic islands.
