Description from Flora of China

Bambusa sanzaoensis W. T. Lin.

Culms 12–13 m, 4.5–5.5 cm in diam., basally slightly flexuose, apically slightly drooping; internodes usually grooved above branches, 35–45 cm, glabrous; wall thick; nodes usually with a persistent ring of stiff, gray-white hairs, basal ca. 4 nodes with a ring of gray-white silky hairs below and above sheath scar, basal node sometimes with short aerial roots; branching from base. Branches solitary on basal 2 nodes, 3 to many on other nodes with primary dominant; dominant branches usually inflated at base and flexuose, lower branchlets sometimes shortened into weak thorns. Culm sheaths deciduous, apex slightly asymmetrical, broadly arched, stiffly dark brown strigose near central base; auricles unequal, larger auricle to 1.5 × size of smaller one, ascending, broadly elliptic, ca. 1.5 cm; oral setae undulate; ligule ca. 7 mm, dentate, shortly fimbriate; blade erect, triangular to ovate-triangular, base ca. 2/3 width of sheath apex. Leaf blade lanceolate to linear-lanceolate, 10–20 × 1.5–2 cm, abaxially densely pubescent, adaxially glabrous. Inflorescence unknown.

Bambusa xiashanensis is similar to B. rutila, but has culm sheaths with central rather than marginal hairs, a more symmetrical apex with more equal auricles, a broader blade, and a taller ligule.
