色季拉山有铁线莲１３种（含变种），其中７种仅分布于东坡，１种仅分布于西坡。其生境类型可分为亚热带森林型、暖温带森林型、温带森林型和林缘广布型，以暖温带森林型和温带森林型的种类居多。观赏类型可分为常绿型、薄萼型和厚萼型，以厚萼型居多。俞氏铁线莲处于濒危状态。
There are 13 species and varieties of Clematis in Shergyla Mountain,and they all are ornamentals.The distribution of Clematis grewiiflora,C.rehderianag,C.montana var. grandiflora,C.metuoensis and C.pseudopogonandra in Linzhi is recorded here for the first time,and C.yui is reported here as new to Tibet.Among the 13 taxa,7 are distributed only on the eastern slope,1 only on the western slope,and 5 on both slopes.They are mainly distributed in the montane warm temperate forest zone and montane temperate forest zone.The differences of moisture and clima tic zones between the eastern and western slopes resulted in their pattern of distribution.Their habitats are divided into 4 types:subtropical forest type,warm temperate forest type,temperate forest type and extensive forest edge type.The Clematis in this area can be divided into evergreen group,thin sepal group and thick sepal group according to the characteristics of flowers and leaves. C.yui is in an endangered status,because its seed ripens in the season of spring drought and also the seed can not take roots readily into the soil due to the presence of thick litters,and because it has to grow for many years to reach the forest crown to set seed.
