top height of 18m and are used for light construction, and also for low quality weaving. The small branches and unraised nodes allow easy splitting. The leaves, although small, are used for fodder and the shoots are sometimes eaten. Despite the lack of branching lower down the culm this species does produce aerial roots on the central branches, and the culm cutting technique of vegetative propagation should be successful. This species is found from 300m to 1,600m. A high proportion of the clumps flowered gregariously in southern Bhutan from 1986 to 1989. The clumps died, but some new clumps regenerated from seedlings.
