1. Tribe BAMBUSEAE - China

POACEAE 23times laciniate, shortly fimbriate; blade deciduous, erect, nearlysymmetrical, initially abaxially yellow-green striped, narrowlyovate-acuminate, base rounded and then extending outward andjoined with auricles for 3–7 mm, nearly 2/3 width of sheathapex. Leaf blade linear-lanceolate, usually 10–15 × 1–1.5 cm,abaxially densely pubescent, adaxially glabrous. Pseudospikeletslinear, 2–5 cm, gemmiferous bracts 2 or 3; florets 5–10;rachilla segments ca. 4 mm. Glume 1, oblong, ca. 6 mm, 9-veined, glabrous, apex acute; lemmas oblong-lanceolate, 1.2–1.4 cm, glabrous, 13–15-veined, apex acute; palea nearly aslong as or slightly shorter than lemma, ciliolate toward apex, 6-veined between and 3-veined on either side of keels; lodicules3, unequal; anterior 2 oblique, ca. 2.7 mm, margins long ciliate,posterior larger, obovate-oblong, ca. 3 mm. Filaments short;anthers ca. 5 mm. Ovary ellipsoid, ca. 1 mm, apex hispidulous;style ca. 1 mm, hispidulous; stigmas 3, ca. 3 mm, hairy. Youngcaryopsis broadly ovoid, ca. 1.5 mm, apex hispidulous, remainsof style base persistent.● River banks, around villages. Guangdong, Guangxi.Two varieties may be recognized in China. In addition, Bambusapervariabilis var. multistriata W. T. Lin (J. Bamboo Res. 16(3): 25.1997) was described from cultivated, sterile material from Guangdong(Guangzhou).1a.

Bambusa longispiculata Gamble in Brandis, Indian Trees668. 1906.花 眉 竹 hua mei zhuCulms 8–12 m, 4–5 cm in diam., basally slightly flexuose,apically erect or slightly drooping; internodes ca. 30 cm, initiallythinly white powdery, glabrous, lower ones with yellowgreenor pale green stripes; wall thick; nodes flat, lower oneswith a ring of gray-white silky hairs below and above sheathscar, basal 1 or 2 nodes with short aerial roots; branching from3rd or 4th node up. Branches several to many per node withcentral dominant. Culm sheaths deciduous, leathery, ribbedstriatewhen dry, glabrous, margins densely ciliate, apex slightlyasymmetrical, broadly arched; auricles unequal, undulate,wrinkled; larger auricle slightly slanted downward for 1/7–1/6of sheath, oblong, 2.5–3 × ca. 1 cm, ends subrounded; smallerauricle 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 slightlyrounded, then extending outward and joined with auricles for4–5 mm, base nearly 2/3 as wide as sheath apex. Leaf bladelinear or linear-lanceolate, 9–15 × 1–1.5 cm, abaxially denselypubescent, adaxially glabrous. Inflorescence not known fromChina.Cultivated. Guangdong [native to Bangladesh and Myanmar].The determination of Chinese gatherings as this species is doubtful.The culms are used for scaffolding.35. Bambusa tuldoides Munro, Trans. Linn. Soc.
