多年生、密丛。秆高90-135厘米。叶鞘无毛；叶舌膜质，长3-4(6-7)毫米，先端截形或碎裂；叶片线形，长25-35厘米，宽约5毫米，边缘粗糙，干时席卷，上面极粗糙，下面平滑。圆锥花序披针形，下部常有间隙，长12-17(22)厘米，中部径1.2-2.5厘米，先端渐尖；小穗狭披针形，长6-7毫米；两颖近等长，锥状披针形，先端长渐尖，沿肋粗糙，第一颖具1脉，第二颖具3脉；外稃长4-5毫米，透明，膜质，先端2齿裂，具3脉，芒由中部以上处伸出，劲直，长2.5-3毫米，基盘之柔毛长5.5-6.8毫米；内稃长2.6-3毫米，透明，膜质，具2脉，脉粗糙；小穗轴延伸于内稃之后，长0.5-0.8毫米，顶端或仅上部簇生少数长丝状柔毛。花期7-8月。
产黑龙江、吉林；东北小兴安岭、完达山、张广才岭、长白山林区为分布中心，松嫩草原也有。常生于林缘、林内沙质地、水湿处或撩荒地上均成片生长。模式标本采自黑龙江尚志县。
