多年生。须根坚韧粗壮。秆直立，高1-3米，直径5-8毫米，节具长髭毛，节之上下部分均被柔毛或白粉。叶鞘下部者长于而上部者短于节间，遍生疣基柔毛，鞘口密生疣基长柔毛；叶舌厚膜质，长3-4毫米，钝圆，具纤毛；叶片长线形，长达80厘米，宽6-12毫米，顶生者退化成锥形，基部渐窄而仅具肥厚的中肋，下面无毛，上面密生疣基柔毛，边缘具锯齿状粗糙。圆锥花序长20-30厘米，主轴被白色柔毛，节具柔毛，常着生4枚分枝；总状花序轴节间与小穗柄长约2.5毫米，先端稍膨大，边缘疏生纤毛；无柄小穗披针形，长约3毫米，基盘具白色或稍带紫色的丝状毛，毛等长或稍短于小穗；第一颖革质，具2脊，有不明显的3脉，顶端钝，上部边缘具纤毛，背部无毛或疏生少数柔毛；第二颖舟形，具3脉，背部无毛；第一外稃长圆形，近等长于颖，边缘具纤毛；第二外稃较窄，稍短于颖，顶端钝，与边缘均具纤毛；第二内稃长约1.5毫米，顶端具长纤毛；鳞被楔形，长与宽均为0.5毫米，顶端截平，具长0.8毫米之纤毛。雄蕊3枚，花药长1.5毫米；柱头长约1.5毫米，自小穗中部以上之两侧伸出。染色体2n=30（Bre-mer，1925），n＝15（Sreenivasan，1984）。花果期8-11月。
产于江苏、江西、广东、广西、四川等省区；多生于山坡草地，耐干旱瘠薄。广泛分布于亚洲东南部的热带地区，印度、缅甸均有。模式标本采自广东。

Perennial from a short stout rhizome. Culms 1–3(–5) m tall, 5–8 mm in diam., nodes bearded, hirsute below panicle. Leaf sheaths hispid with tubercle-based hairs; leaf blades 1–1.5 m × 0.6–2 cm, adaxial surface thinly hispidulous, abaxial surface glabrous, margins scabrid, tapering to midrib at base, apex attenuate; ligule 3–4 mm, rounded. Panicle narrowly elliptic-oblong in outline, 20–50 cm, copper brown or purplish brown, axis white-pilose; racemes arising almost from main axis, stiffly ascending, densely spiculate, lowest 6–10 cm; rachis internodes 1.7–2.5 mm, ciliate. Spikelets 2.5–3 mm, brown, glossy; callus hairs about equaling spikelet, white or purplish; lower glume narrowly lanceolate-oblong, leathery, back glabrous or thinly pilose below middle, keels scabrid and margins ciliate near apex, apex narrowly truncate; lower lemma equal to glumes; upper lemma narrow, truncate, awnless. Anthers 3, 1.2–1.5 mm. Fl. and fr. Aug–Nov. 2n = 30.
