Calamagrostis pseudaphragmites (Hall. f.) Koel. Descr. Gram. 106. 1802; 禾本科图说526.图452. 1959; 中国高等植物图鉴5: 108.图7045. 1976; 秦岭植物志1(1): 140. 1976; 江苏植物志 (上): 199.图334. 1976. ——Arundo pseudophragmites Hall. f. in Arch. Bot. Roemer 1(2): 11. 1796.
秆直立，高40-100厘米，径1.5-4毫米。叶鞘平滑无毛，或稍粗糙，短于节间，有时在下部者长于节间；叶舌膜质，长4-9毫米，长圆形，顶端钝而易破碎；叶片长10-30厘米，宽1.5-5(7）毫米，扁平或内卷，上面及边缘粗糙，下面平滑。圆锥花序长圆状披针形，疏松开展，长10-20(35）厘米，宽(2)3-5厘米，分枝簇生，直立，细弱，稍糙涩；小穗长5-7毫米，草黄色或紫色；颖线状披针形，成熟后张开，顶端长渐尖，不等长，第二颖较第一颖短1/4-1/3，具1脉或第二颖具3脉，主脉粗糙；外稃透明膜质，长3-4毫米，具3脉，顶端全缘，稀微齿裂，芒自顶端或稍下伸出，细直，细弱，长1-3毫米，基盘的柔毛等长或稍短于小穗；内稃长为外稃的1/3-2/3；雄蕊3，花药长1-2毫米。花果期7-9月。
广布于我国东北、华北、西北、四川、云南、贵州、湖北等地区诸省。生于山坡草地或河岸阴湿之处，海拔350-2500米。欧亚大陆温带区域都有分布。模式标本采自瑞士。
可作饲料；生活力强，可为防沙固堤的材料。

Arundo pseudophragmites A. Haller, Arch. Bot. (Leipzig), 1(2): 11. 1797; Calamagrostis nepalensis Nees ex Steudel.
Perennial, tufted, rhizomatous; rhizomes spreading. Culms erect, 40–150 cm tall, 1.5–4 mm in diam., 2–6-noded, scabrid below panicle. Leaf sheaths smooth or scabrid; leaf blades flat or weakly inrolled, 10–30 cm, 2–5(–7) mm wide, adaxial surface and margins scabrid, abaxial surface smooth; ligule 4–10 mm, obtuse or lacerate. Panicle oblong-lanceolate, rather lax, 10–30 × 2–5 cm, primary branches distinct, nodding; branches in dense whorls, scabrid. Spikelets 5–9 mm, yellowish green or purple; glumes linear-lanceolate, unequal, upper glume 2/3–3/4 length of lower glume, keel scabrid, apex acuminate-subulate; callus hairs 2–3 times length of lemma; lemma about 1/2 as long as glumes, 3–4 mm, 3-veined, apex entire or 2-denticulate; awn arising just below lemma apex, 1–3 mm, scarcely projecting from glumes, straight; palea 1/2–2/3 as long as lemma. Stamens 3; anthers 1–2 mm; rachilla not extended. Fl. and fr. Jul–Sep.
Damp grassy slopes, near riversides; 300–2500 m. Gansu, Guizhou, Hubei, Nei Mongol, Qinghai, Sichuan, Xinjiang, Xizang, Yunnan and NE China [Bhutan, India (Darjeeling), Japan, Kazakhstan, Korea, Pakistan, Turkmenistan, Kyrgyzstan, Mongolia, Russia, Tajikstan, Uzbekistan; SW Asia, Europe].
