根状茎短。秆密丛生，纤细，稍坚挺，高5-40厘米，粗1-1.5毫米，钝三棱形，基部密生栗褐色宿存叶鞘。叶短于秆，对折呈线形，宽1-2毫米，稍坚挺，腹面具沟。花序穗状，但基部常有1-2个短的分枝，圆柱形，少有长圆状圆柱形，长1-3.5厘米，粗3-5毫米；苞片鳞片状，顶端具长芒；支小穗多数，密生，顶生的数个雄性，其余的均为雄雌顺序，在基部雌花之上具2-5朵雄花。鳞片长圆形或长圆状披针形，长3.5-4.5毫米，顶端圆、钝或渐尖，纸质，两侧淡褐色或褐色，具宽的白色膜质边缘或无，中间黄色，具3条脉，下部的数枚其中脉常延伸成芒。先出叶长圆形，长3-4.5毫米，膜质，下部淡褐色或褐色，上部白色，腹面边缘分离至3/4处，背面具光滑的2脊，脊间无脉。小坚果卵形、长圆形或倒卵状长圆形，扁三棱形，长2-3毫米，黄色，干后变为褐色，基部几无柄，顶端骤缩成短喙；花柱基部不增粗，柱头3个。花果期5-9月。
产于青海东南部、四川西部和北部、云南西北部、西藏东部；生于亚高山草甸、林间和林边草地、湿润草地，海拔2300-4300米。模式标本采自四川省盐源县雅砻江边。

Kobresia handel-mazzettii K. V. Ivanova; K. longearistita P. C. Li; K. pinetorum F. T. Wang & Tang ex P. C. Li.
Rhizomes short. Basal sheaths prominent and persistent, pale brown, dull or slightly shiny, not fibrillose, not retaining dried leaf blades. Culms densely tufted, stiffly erect, obtusely trigonous, 5-20(-40) cm, slender, 0.7-1.3 mm in diam. Leaves basal, shorter than culms; blade folded or margin involute, stiff, 1-2 mm wide, midrib not distinct abaxially. Inflorescence usually a dense spike (occasionally with 1 or 2 branches at base), greenish brown, cylindric, 1-3.5 × 0.3-0.6 cm; lowest involucral bract glumelike, apex long or shortly aristate; terminal few spikelets male, lower ones bisexual with 1 female and 2-5 male flowers. Glumes brown, with yellowish green to green midvein, oblong-ovate to oblong-lanceolate, 3-4.5 × 1.5-2.5 mm, papery, midvein broad, margin usually narrowly hyaline, apex usually subacute, sometimes shortly aristate. Prophylls yellowish brown, oblong, 2-4.5 × 1-1.6 mm, membranous, 2-keeled, keels smooth or slightly scabrid, sometimes veined between keels, margins free nearly to base, apex rounded or acute. Nutlets yellowish, narrowly obovoid, compressed trigonous, 2.1-3 × 1-1.3 mm, not beaked, subsessile. Stigmas 3. Fl. and fr. May-Sep.
● Grassy slopes, alpine meadows, swampy meadows and marshes by lakes, dry limestone slopes, forest (including Pinus) understories, Quercus scrub; 2300-4300 m. Gansu, Qinghai, Sichuan, Xizang, Yunnan.
