Bor.-Amer. 1: 73. 1803.青 篱 竹 属 qing li zhu shuZhu Zhengde ( 朱 政 德 Chu Cheng-de), Li Dezhu ( 李 德 铢 ); Chris StapletonSmall to arborescent bamboos, spreading or loosely clumped. Rhizomes leptomorph. Culms diffuse to pluricaespitose, suberectto drooping, 1–7(–13) m tall, 0.5–4(–6) cm thick; internodes terete to flattened on one side above branches. Branch buds tall, with orwithout promontory, within 2-keeled prophyll, always open at front. Branches (1 or)2–5(–7), subequal. Lateral branch axes alwayssubtended by sheaths, without replication of lateral branches. Culm sheaths deciduous to persistent, blade usually recurved orreflexed, lanceolate, articulate. Leaf sheaths persistent; blade oblong-lanceolate or narrowly lanceolate, small to medium-sized, withoutmarginal necrosis in winter, arrangement random, transverse veins distinct. Inflorescence an open panicle or raceme, floweringbranches usually subtended by tiny bracts. Spikelets several to many flowered, slender; rachilla internodes extended, disarticulating.Glumes 1 or 2, mucronate; lemma similar to glumes; palea 2-keeled, apex obtuse; lodicules 3. Stamens 3; filaments free, slender;anthers yellow. Style usually very short; stigmas 2 or 3, plumose. Caryopsis dry, oblong. New shoots May–Jun.About eight species: SW China, E Himalayas, Vietnam, SE United States; five species (four endemic) in China.In FRPS (9(1), 1996), Arundinaria was considered a unispecific, North American genus with no Asian representatives at all. A much broadertreatment of the genus has also been advocated by several authors. In this treatment the morphologically closest Asian species under Arundinaria,those from Bashania and Sarocalamus, are included. Arundinaria subg. Arundinaria differs in its persistent culm sheaths and larger florets and isrestricted to the SE United States.1a.
