多年生，簇生草本。秆直立，高20-60厘米。叶鞘密生疣基长柔毛，多聚于秆基，叶舌极短，顶端具长睫毛；叶片质硬，线形，长7-25厘米，宽2-5毫米，顶端渐尖，两面密被疣基长柔毛；干时常内卷。圆锥花序开展，长10-30厘米，稀疏，分枝纤细，坚挺，具糙毛；小穗卵状椭圆形，长2.5-4毫米，绿色或紫褐色，无毛，有长柄，顶端疏生细硬毛；第一颖宽卵形，长约为小穗的1/2-2/3，顶端尖，具5脉，有时侧脉不明显；第二颖与第一外稃等长，亦与小穗等长，顶端喙尖，具7脉；第一外稃具9脉，顶端喙尖，其内稃较短小，薄膜质，具2脉；第二小花卵状椭圆形或长圆状披针形，长约2.5毫米，顶端钝，表面平滑，光亮，灰白色至乳黄色；鳞被较厚，多脉，长约0.3毫米，宽约0.45毫米，局部折叠。染色体2n=36（Larsen，1963）。花果期5-10月。

Panicum curviflorum Hornemann var. suishaense (Hayata) Veldkamp; P. suishaense Hayata; P. trypheron Schultes var. suishaense (Hayata) C. C. Hsu.
Perennial, tufted. Culms erect, 25–60 cm tall, nodes glabrous. Leaves mostly basal; leaf sheaths pilose to hispid; leaf blades linear, flat, 12–50 × 0.3–0.8 cm, pilose, base narrowed, apex acuminate; ligule a ciliate collar.
