多年生。须根稀疏且较长，柔韧。茎直立或稍倾斜，丛生，光滑无毛，高50-80厘米，具2-3节，节常紫红色。叶鞘稍松弛，无毛，短于节间；叶舌透明膜质，长5-8毫米，渐尖；叶片扁平或对折，上面粗糙，下面光滑无毛，基部者稠密，长达11厘米，宽2-3毫米，茎生者少而短，长3-8厘米。圆锥花序紧缩，长卵形或狭椭圆形，长8-15厘米，草黄色或灰绿色，有时褐色，每节分枝多数丛生，分枝短缩，长达5厘米，向上直立，上部着生较多小穗；小穗长4.5-5毫米，含2-3小花；小穗轴节间长约1毫米，被近等长的柔毛；颖短于小穗，两颖近相等或第一颖稍短于第二颖，长3.5-5毫米，先端尖或钝，具微细齿，第一颖具1脉，第二颖具3脉；外稃等于或稍短于第一颖，先端平截而呈啮蚀状，基盘两侧的毛长达稃体的1/3或1/2，自稃体背中部或稍低处伸出1芒，其芒短于外稃，直立，或有时无芒；内稃略短于外稃，具2脊。花期6-8月。
产新疆天山。生于海拔1800-3100米的高山草地、沼泽地及潮湿处。分布于帕米尔东部及西部。模式标本采自帕米尔。

Deschampsia cespitosa subsp. pamirica (Roshevitz) Tzve-lev
帕米尔发草 pa mi er fa cao
Deschampsia pamirica Roshevitz in Komarov, Fl. URSS 2: 750. 1934.
Culms 30–80 cm tall. Leaf blades 2–3 mm. wide. Panicle contracted but not spikelike, narrowly elliptic or narrowly oblong in outline, erect, 6–15 cm, greenish yellow or gray-green, infrequently tinged violet-brown; branches suberect, smooth, lowest up to 5 cm. Spikelets 4.5–5 mm; glumes slightly shorter than or subequaling adjoining lemmas, apex obtuse, often lacerate; lemmas awned from slightly below middle to lower 1/4, or awnless; awn shorter than lemma. Fl. Jun–Aug.
Swampy, often saline, montane grasslands; 1800–3100 m. Xinjiang [Tajikistan (Pamirs)].
This is a local variant, intermediate between typical Deschampsia cespitosa, with an open panicle, and D. koelerioides. This subspecies is a taller, stouter plant than D. koelerioides, with a paler, less dense panicle, and occurs at somewhat lower altitudes.
