  Alopecurus himalaicus Hook. f. Fl. Brit. Ind. 7: 238. 1897; Ovczinn. in Kom. Fl. URSS 2: 144. 1934; Bor, Grass. Burma Ceyl. Ind. Pakist. 393. 1960; Tzvel. Poac. URSS 374. 1976.
  多年生。秆直立,单生或少数丛生,高约15厘米,具3节,光滑。叶鞘大多长于节间,上部者膨大,光滑;叶舌膜质,长约3毫米,先端边缘有齿;叶片长约6厘米,宽达5毫米,先端渐尖,上面粗糙,下面光滑。圆锥花序长圆形,长约2.5厘米,宽约8毫米,灰绿色;小穗卵形,长4-4.5毫米;颖近于膜质,下部连合,上部略叉开,先端渐尖呈芒尖,脊上具长达2毫米的纤毛,两侧具柔毛;外稃短于颖片,先端尖,芒自下部伸出,长约4毫米(幼株),劲直;雄蕊3,花药黄色,长约2毫米。花期6月。
  产新疆南部(塔什库尔干县)。生于海拔3000-4100米的河滩湿地。在苏联,伊朗,克什米尔、西喜马拉雅地区也有分布。模式标本采自克什米尔。本种为我国分布新记录。
  由于标本系幼株(花期),因而各部分之大小,均显然小于原记载,但就其结构而言,与本种却是相符的。
