The genus Schizostachyum is extensively developed in the Phil- 
ippines. Among the bamboos it has by far the largest number 
of species, and presents several of the most common and widely 
distributed bamboos in the Archipelago. All of the species are 
indigenous, and none of them are cultivated. The genus contains 
both erect, thin-walled species, and scandent, thick-walled ones, 
several of which are used for special purposes. None of the 
species are of large size. Most of them are sylvan or subsylvan 
and usually do not occur in the open settled areas. Several 
of them are gregarious and in some provinces occupy rather 
large areas of land to the practical exclusion of other vegetation.

Local names: Boho (Isinai and Mindanao); bagdkai (Leyte); bagakan 
(Palawan).
