Bambusa diaoluoshanensis Chia et Fung


Description from Flora of China

Culms ca. 10 m, 4–5 cm in diam., basally slightly flexuose, apically pendulous; internodes 25–30 cm, initially stiffly brown strigose; wall thick; lower nodes with rings of stiff, pale brown hairs and white powder below sheath scar, basal ca. 3 nodes also with a ring of gray-white silky hairs and sometimes aerial roots above sheath scar; branching from base. Branches solitary at basal ca. 3 nodes, 3 on mid-culm, many on upper culms with primary dominant; branchlets of lower branches sometimes shortened into weak thorns. Culm sheaths deciduous, stiffly dark brown hairy, apex asymmetrical, broadly arched; auricles extremely unequal; larger auricle to 4 × size of smaller one, narrowly oblong, ca. 5 mm; smaller auricle subelliptic, usually covered or pressed against base of blade; oral setae undulate; ligule ca. 3 mm, finely dentate, shortly fimbriate; blade erect, narrowly triangular, base rounded, to 8/9 width of sheath apex. Leaf blade linear-lanceolate to lanceolate, usually 7.5–16 × 1.3–1.8 cm, abaxially densely pubescent, adaxially glabrous. Inflorescence unknown.

Bambusa diaoluoshanensis is similar to B. ramispinosa, but has hairs on the culm internodes and sheaths and an asymmetrical culm sheath apex with more unequal auricles.
