Inflorescences in the form of panicles on leafy twigs with clusters of up to 18 spikelets on each segment. The spikelet is oval lanceolate, 8-11 cm long, 3 mm wide, 4 perfect florets and one flawless tip floret.

Black bamboo lives in humid tropical regions with rainfall of 1500-3700 mm per year, humidity of more than 70% and temperatures of 20-32C. Generally grows on latosol soils, red laterite and reddish brown, but prefers drier chalky soils.

The density of wet reeds is 0.37-0.48 and dry is 0.65. Dry reed moisture content is 16.8%. Black bamboo is used as a material for making musical instruments, household items, furniture, halls, handicrafts and various types of weaving. Bamboo shoots are often cooked as a vegetable.
