Pseudosasa pubiflora (Keng) Keng fil. ex D. Z. Li & L. M. Gao

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.

Culms ca. 1 m, 2–3 mm in diam.; internodes terete, woolly or tomentose below nodes; nodes weakly prominent. Branches 1–3 per node, elongated, slender. Culm sheaths persistent; auricles and oral setae absent; ligule extremely short, nearly absent; blade deciduous, small. Leaves 1 or 2 per ultimate branch; sheath glabrous or apically slightly hairy, margins ciliate; auricles and oral setae weakly developed or absent; ligule extremely short; blade lanceolate or elliptic-lanceolate, ca. 15 × 19 cm, abaxially setulose, adaxially glabrous, one margin roughly hairy. Inflorescence paniculate, lateral; spikelets ca. 10; rachilla glabrous or hairy at base; pedicel densely puberulous; florets 2 or 3, loosely arranged. Glumes 2; lemma ovate, adnately hairy; palea about as long as lemma, keels densely hairy; lodicules 3, subequal. Ovary glabrous; stigmas 2. Caryopsis unknown. New shoots Apr.

* Slopes; low elevations. N Guangdong, S Hunan, S Jiangxi.
