POACEAE 135● Guangxi.Gelidocalamus albopubescens W. T. Lin & Z. J. Feng (Acta Phytotax.Sin. 30: 561. 1992), described from Guangdong (Guangning),may be a synonym of this species.9.

Culm sheaths persistent, pinkwhen fresh, initially hirsute; auricles absent; oral setae minute;ligule slightly concave, ca. 1 mm, ciliate; blade erect, linear-lanceolateor subulate, base ca. 1/3 as wide as sheath apex. Leaves1 per ultimate branch; pseudopetiole 4–5 mm; blade narrowlylanceolate to oblong, 17–31 × 2–4 cm, abaxially hirsute, secondaryveins 6–8-paired. Inflorescence unknown.Culms to 1 m, 0.3–0.6 cm in diam.; internodes 10–15 cm,● Zhejiang.27. FERROCALAMUS Hsueh & P. C, Keng, J. Bamboo Res. 1(2): 3. 1982.铁 竹 属 tie zhu shuLi Dezhu ( 李 德 铢 ); Chris StapletonShrubby, self-supporting to scrambling bamboos. Rhizomes leptomorph. Culms pluricaespitose, erect; internodes terete, long,thick walled, with a ring of white hairs below nodes; nodes prominent. Branches at mid-culm solitary, erect, parallel to and nearly asthick as culm; at upper nodes 3–5. Culm sheaths persistent, leathery at base, thinner at apex; auricles small or absent; oral setaedeveloped; blade reflexed, leaflike or small. Leaf blade large; auricles absent or present with oral setae; ligule short; transverse veinsdistinct. Inflorescence a large panicle on leafy flowering branches. Spikelets very many, slender, 3–10-flowered, followed by a sterilefloret. Glumes 2, obtuse. Rachilla articulate; florets falling separately; lemma leathery with many veins and obscure transversevenation. Palea longer than lemma, 2-keeled, apex emarginate. Lodicules 3. Stamens 3; filaments free. Ovary glabrous; styles short;stigmas 2, plumose. Fruit berrylike, succulent with thickened, fleshy pericarp but without hardened endocarp, ovoid or subglobose.2n = 48*.● Two species: China.In the past, the culms of Ferrocalamus were used for making arrows. This rare endemic genus is endangered by habitat destruction, as it isknown only from a very limited number of localities.1a.

Culm sheaths drying entire on culms, initially yellowgreen,leathery, densely brown or dark brown hairy, apexpapery; auricles absent; ligule truncate, 2–3 mm; blade reflexed,initially green, turning brown in age, broadly lanceolate or oblong-lanceolate.Leaf sheath glabrous; auricles absent; oralsetae deciduous, 1–2 cm; blade broadly lanceolate, 30–35 × 6–9cm, base cuneate. Panicles 30–45 cm. Spikelets 1.4–1.8 cm;florets 3–10; rachilla internodes glabrous. Glumes 3–5 mm;lemma ca. 7 mm; lodicules ca. 3 mm. Stamens unknown. Styleshort; stigmas ca. 1.5 mm. Fruit dark brown, ca. 2 cm, ovoid orsubglobose. New shoots Mar–May, fl. Apr.● Montane broad-leaved forests; 900–1200 m. S Yunnan (Jinping,Luchun).2. Ferrocalamus rimosivaginus T. H. Wen, J.

Arnold Arbor. 6: 148. 1925.箬 竹 属 ruo zhu shuWang Zhengping ( 王 正 平 Wang Cheng-ping); Chris StapletonShrubby bamboos. Rhizomes leptomorph, with running underground stems. Culms pluricaespitose, nodding; internodes usuallyterete, usually with a dense, persistent, apical, yellow-brown tomentose to setaceous ring below nodes, rarely apically glabrous; wallthick; nodes usually flat, sometimes prominent. Branches usually solitary, nearly as thick as culms. Culm sheaths persistent, usuallyshorter than internodes, papery or nearly leathery; auricles usually developed; blade usually recurved, lanceolate. Leaf sheathscylindrical, very thick, smooth. Leaves usually large relative to culm size, transverse veins distinct. Inflorescence largely ebracteate,
