Bamboo

The determination of Chinese gatherings as this species is doubtful.

The culms are used for scaffolding.

Culms 8–12 m, 4–5 cm in diam., basally slightly flexuose, apically erect or slightly drooping; internodes ca. 30 cm, initially thinly white powdery, glabrous, lower ones with yellow-green or pale green stripes; wall thick; nodes flat, lower ones with a ring of gray-white silky hairs below and above sheath scar, basal 1 or 2 nodes with short aerial roots; branching from 3rd or 4th node up. Branches several to many per node with central dominant. Culm sheaths deciduous, leathery, ribbed-striate when dry, glabrous, margins densely ciliate, apex slightly asymmetrical, broadly arched; auricles unequal, undulate, wrinkled; larger auricle slightly slanted downward for 1/7–1/6 of sheath, oblong, 2.5–3 × ca. 1 cm, ends subrounded; smaller auricle suborbicular, ca. 1/2 size of larger; oral setae slender, undulate, densely covering margins of auricles; ligule 4–5 mm, margin irregular, finely dentate and laciniate, densely ciliolate; blade erect, slightly asymmetrical, ovate-triangular, base slightly rounded, then extending outward and joined with auricles for 4–5 mm, base nearly 2/3 as wide as sheath apex. Leaf blade linear or linear-lanceolate, 9–15 × 1–1.5 cm, abaxially densely pubescent, adaxially glabrous. Inflorescence not known from China.
