Yunnan. 2: 96. 1980), but that name was notvalidly published.34. Chimonobambusa montigena (T. P. Yi) Ohrnberger,Bambusbrief 1990(4): 11. 1990.荆 竹 jing zhuQiongzhuea montigena T. P. Yi, J. Bamboo Res. 9(3): 28.1990.Culms 1.5–2.8 m, 0.7–1.4 cm in diam.; internodes terete,(5–)13–14(–19) cm, grooved above branches, initially sparselywhite powdery; wall 3–4 mm; nodes raised into ring; sheathscar initially densely yellow-brown setose. Branches 3–5 pernode. Culm sheaths deciduous, triangular-elliptic, shorter thaninternodes; leathery, yellow setose at base, margins initiallygray ciliate, longitudinal veins distinct; auricles absent; liguletruncate, 0.5–0.8 mm; blade erect, triangular or subulate, 2.5–7mm, margins ciliate. Leaves 2–5 per ultimate branch; auriclessmall; oral setae initially several; ligule arcuate, ca. 1 mm;blade lanceolate, (4.5–)8–14.5 × (0.8–)1.3–2.6 cm, transverseveins distinct. Inflorescence on leafless branches or terminal toleafy branchlets, 1–4 single pseudospikelet racemes grouped inloose fascicles, subtended by several, gradually enlarged bracts.Spikelets 5–7-flowered, 2–3.2 × 0.3–0.5 cm. Glume 1, 1–2.2cm; rachilla articulate, internodes 2–4 mm; lemma (7–)9–13mm; palea 6–9 mm, apex acute. Anthers yellow, 5–6 mm.Ovary ovoid; style 1; stigmas 2 or 3. Fruit a nutlike caryopsis.New shoots late Apr to early May, fl. and fr. Jul–Sep.● Broad-leaved forests; 2300–2500 m. NE Yunnan.33. SHIBATAEA Makino ex Nakai, J. Jap. Bot. 9(2): 83. 1933.鹅 毛 竹 属 e mao zhu shuWang Zhengping ( 王 正 平 Wang Cheng-ping); Chris StapletonShrubby bamboos. Rhizomes leptomorph, with running underground stems. Culms pluricaespitose, less than 1 m, distallyflexuose; internodes flattened on branching sides; nodes 2-ridged. Branches 3–5, slender, often without secondary branchlets, usuallywith persistent membranous prophylls and branch sheaths. Culm sheaths deciduous, papery, transverse veins distinct; auricles absent;ligule well developed; blade lanceolate to subulate, small. Leaves usually solitary on each branchlet; sheaths contiguous with branchlets,thickened, petiole-like, rarely 2 or more with median sheaths exceeding proximal and distal ones; auricles absent; ligule usuallylong, conical and highly involute in solitary or upper leaves; blade very broadly lanceolate to narrowly lanceolate, transverse veinsdistinct. Inflorescence bracteate, partially iterauctant, composed of 1-spikeleted racemes gathered in fascicles with a spathate prophyll,0 or 1 empty bract, and 0–3 gemmiferous bracts. Spikelets 2–7-flowered, lower 1 or 2 fertile, upper ones sterile. Glumes usuallyabsent; lemma membranous, broadly lanceolate, apex acuminate; palea 2-keeled; lodicules 3, narrowly obovate, membranous.Stamens 3. Style 1; stigmas 3, plumose. Fruit a caryopsis.● Seven species: China.In addition to the species treated below, Shibataea pygmaea F. Maekawa (J. Jap. Bot. 19: 150. 1943) was described from Jiangxi. This specieswas based on abnormal material, and it is difficult to confirm its identity, since no Shibataea has been found at the type locality. Shibataea tumidinodaT. H. Wen (J. Bamboo Res. 7(1): 23. 1988) was described from Fujian. This species was based on a poor gathering, and its identity is uncertain.These bamboos are usually cultivated as ornamentals. One species was introduced to Japan at an early date and has been widely planted there.1a. Leaf blade narrowly lanceolate with a long caudate tip, length 6–10 × width.2a.
