摘要
基于标本和文献,对新疆丝瓜藓属(Pohlia Hedw.)进行全面修订,更正了此前部分标本的错误鉴定,将卵蒴丝瓜藓(Pohlia proligera)和糙枝丝瓜藓(P.camptotrachela)从本区名录中移除,将多态丝瓜藓(P.minor)归并为丝瓜藓多态变种(P.elongata var.greenii)的异名,新增新疆丝瓜藓属新纪录2种:拟长蒴丝瓜藓(P.longicollis)和小丝瓜藓狭叶变种(P.crudoides var.revolvens)。现已知新疆丝瓜藓属有8种,2变种,种数约占全国的1/3。通过分析各个种的识别特征、与相近种的区别和生境,编制了新疆丝瓜藓属分种检索表。
The phylogenetic position of the genus Pohlia Hedw. is uncertain yet. Traditionally, the genus was placed in the subfamilies Bryoideae or Pohlioideae of generalized family Bryaceae （ sensu lato）. Then it was accom- modated into family Mniaceae or Mielichhoferiaceae. In this paper, a revision of Pohlia in Xinjiang Uygur Autono- mous Region, China was provided based on the specimens and references. Two species, P. proligera and P. camp- totrachela were deleted from the moss checklist of the region. Additions to two mosses in Xinjiang, P. longicoUis and P. crudoides var. revolvens. P. minor were reduced to a synonym as P. elongata var. greenii. Pohlia in Xin- jiang, including 8 species and 2 varieties, was newly updated in the checklist. About one third species of the total in China were distributed in Xinjiang. The diagnostic characteristics and habitats for the species were provided in the paper. The voucher specimens were deposited in the herbarium of Hebei Normal University （HBNU） , herbari- um of Xinjiang University （ XJU）, and Chinese National Herbarium, Chinese Academy of Sciences （PE）.
