The combination Pseudosasa pubiflora was not previously validly published by P. C. Keng (Claves Gen. Sp. Gram. Prim. Sin. 154. 1957 and Fl. Ill. Pl. Prim. Sin. Gram. 32. 1959) because a clear and direct reference to the basionym was not given.

The woolly internode apex is unusual in Pseudosasa and rather suggestive of Indocalamus.
