| 摘 要： | 在标本观察和野外调查的基础上，对西藏的嵩草属Kobresia植物进行了分类学修订，共确认了36种和1亚种。更正了6个类群的学名，它们正确的名称是K. esenbeckii，K. fissiglumis，K. gammiei，K. littledalei，K. myosuroides ssp. bistaminata和K. vaginosa。有13个名称，即K. angusta，K. cercostachys var. capillacea，K. clarkeana，K. curticeps var. gyirongensis，K. deasyi，K. glaucifolia，K. hookeri，K. nudicarpa，K. prainii var. elliptica，K. seticulmis，K. stenocarpa，K. stenocarpa var. simplex和K. williamsii处理为异名，其中K. prainii var. elliptica，K. glaucifolia和K. stenocarpa var. simplex为新异名。发现了西藏分布的一个新记录种密穗嵩草K. handel-mazzettii。还收录了最近发表的假钩状嵩草K. pseuduncinoides和阔鳞嵩草K. woodii。此外，重新编制了西藏嵩草属分种和亚种检索表，并较为详细地登记了各类群在西藏的分布地点。

| Abstract: | The genus Kobresia in Xizang (Tibet) is revised taxonomically on the basis of both herbarium and field observations. Thirty-six species and one subspecies are recognized. The names of six taxa are corrected, and the six correct names are K. esenbeckii, K. fissiglumis, K. gammiei, K. littledalei, K. myosuroides ssp. bistaminata and K. vaginosa. Thirteen previously recognised taxa, K. angusta, K. cercostachys var. capillacea, K. clarkeana, K. curticeps var. gyirongensis, K. deasyi, K. glaucifolia, K. hookeri, K. nudicarpa, K. prainii var. elliptica, K. seticulmis, K. stenocarpa, K. stenocarpa var. simplex and K. williamsii, are treated as synonyms. K. prainii var. elliptica, K. glaucifolia and K. stenocarpa var. simplex are new synonyms. K. handel-mazzettii is a new record to Xizang. Two species newly published, K. pseuduncinoides and K. woodii, should be added to the flora of Xizang. A new key to species and subspecies, and the information of the distribution sites of each taxon in Xizang are given. |
