This bamboo is a common component of coniferous and broadleaved forest in temperate parts of eastern and central Bhutan, from 1,700m to 2,600m. It is very similar to the western species Y. maling, but it is usually larger. This is a very vigorous bamboo, reaching up to 8m in height and 2cm in diameter, with internodes up to 40cm long. The combination of a dense ring of hairs at the base of the culm sheaths, no thickened transparent band on the leaf edges, and very erect leaf sheath bristles with no auricles, distinguishes this bamboo from other Yushania species in Bhutan. The culm sheaths and the leaf sheaths are quite similar to those of Borinda grossa, but the culms are rough and do not have the fine ridges seen on
