多年生土生植物。茎直立或斜生，高3-25厘米，中部直径1-3毫米，枝连叶宽5-16毫米，1-4回二叉分枝，枝上部常有芽胞。叶螺旋状排列，密生，斜向上或平伸，披针形，基部与中部近等宽，通直，长2-10毫米，中部宽0.8-1.8毫米，基部截形，下延，无柄，先端急尖，边缘平直不皱曲，全缘，两面光滑，具光泽，中脉背面不显，腹面可见，革质至草质。孢子叶与不育叶同形；孢子囊生于孢子叶腋，不外露或两端露出，肾形，黄色。

产我国东北、西北、西南及台湾。生于海拔1900-5000米的高山草甸上、石缝中、林下、沟旁。广布欧、亚、美、大洋洲。模式标本采自北欧。

通过对本种在欧洲斯洛伐克、瑞士、意大利、奥地利的实地考察，我们认为H.appressa (Desv. ) Love et Leve与本种不可分。

本种叶片边缘内卷，先端渐尖。
