1. Tribe BAMBUSEAE - China

POACEAE 179veined, apex acuminate with an awnlike tip, first lemma 1–1.2(–1.6) cm; palea shorter than lemma, 0.6–1.1 cm, denselyhirsute. Anthers 4.5–5.5 mm. Stigmas (1–)3. New shoots Apr–May, fl. Apr–May. 2n = 48*.● Forests, scrub, cultivated; below 1300 m. Guangdong, Guangxi,Henan, Hubei, Jiangxi, Shaanxi, Yunnan, Zhejiang [introduced in Europeand North America].The shoots are edible, but the culms are brittle and not suitable forweaving. The straight culms, interesting culm sheath auricles, and pendulousfoliage make this species suitable as an ornamental.45. Phyllostachys rivalis H. R. Zhao & A. T.

Bull. 9: 41.1940) and P. dubia Keng (Sinensia 11: 407. 1940, “dubius”) may befurther synonyms of this species.Phyllostachys heteroclada is widely cultivated for its high-qualityculms, which are split for weaving articles such as the famous bamboomats produced in Yiyang, Hunan.48.
