多年生。秆密丛生，直立，高90-120厘米，基部稍压扁，一般具有5-6节，叶鞘基部相互跨覆，长于节间数倍，而上部叶鞘又比节间短。下部叶鞘粗糙并疏生刺毛，鞘口具长柔毛；叶片细长丝状，向外弯曲，长10-40厘米，宽1-2.5毫米。圆锥花序开展，长15-35厘米，宽6-9厘米，花序主轴及分枝单生、对生或轮生，平展或斜上升，二次分枝和小，穗柄贴生紧密，小穗柄极短，分枝腋间有毛，小穗长6-11毫米，宽1.5-2毫米，有5-12小花，排列较疏松，铅绿色；颖披针形，先端渐尖，均具1脉，第一颖长约1.5毫米，第二颖长约2.5毫米；第一外稃长约2.5毫米，广长圆形，先端尖或钝，具3脉；内稃与外稃近等长，长约2.3毫米，具2脊，无毛，先端圆钝，宿存或缓落；雄蕊3枚，花药长约1.2毫米。染色体数目变异较大，通常2n=20-80，亦间有2n=42或63。花果期4-9月。
原产非洲。我国江苏、湖北、广西均有栽培。模式标本采自非洲好望角。
常栽培作牧草或布置庭园。

弯叶画眉草 wan ye hua mei cao
Poa curvula Schrader, G?tt. Gel. Anz. 3: 2073. 1821.
Perennial. Culms densely tufted, erect, 80–120 cm tall, 5–6-noded. Leaf sheaths scabrous with retrorse hairs at lower part, glabrous upward, shorter than internodes, long pilose along the summit; leaf blades elongate, involute, attenuate to a fine point, arcuate spreading, scabrous, (5–)10–40 cm × 1–2.5(–3) mm. Panicles open, 12–35 × 6–9 cm; branches solitary or in pairs, ascending, naked at base, at least the lower densely pilose in axils. Spikelets gray-green, (4–)6–11 × 1.5–2 mm, 5–16-flowered. Glumes lanceolate, apex acuminate, 1-veined, lower glume 1.2–1.5 mm, upper glume 1.8–2.5 mm. Lemmas broadly oblong, apex acute or obtuse, veins prominent, lower lemma 2–2.5 mm. Palea subequal to lemma, 2-keeled, persistent or tardily deciduous. Stamens 3; anthers ca. 1.2 mm. Caryopsis ellipsoid to obovoid, dorsally compressed, adaxial surface with a shallow, broad groove or ungrooved, smooth, mostly translucent, light brown, 1–1.7 mm. Fl. and fr. Apr–Sep. 2n = 20, 42, 63, 80.
Commonly cultivated for ornament. Fujian, Guangxi, Hubei, Jiangsu, Xinjiang, Yunnan [native to Africa].
This species is used for fodder and as an ornamental grass.
