摘　　要：由于虎耳草属植物在生态学、形态学、细胞学等方面的变异很大,增加了物种鉴定的难度,导致地方植物志中多有遗漏之处。《青海植物志》收录了虎耳草属植物32种。通过野外考察和标本鉴定,发现了青海虎耳草属植物的6个新分布种——狭叶虎耳草、阿墩子虎耳草、密花虎耳草、珠芽虎耳草、沼地虎耳草和篦齿虎耳草。《青海植物志》和《Flora of China》均没有记录这6个物种在青海省的分布。Due to the complex diversity in ecology, morphology and cytology of Saxifraga , it is difficult to identify the species, which results to an incomplete collection in local floras. Thirty-two Saxifraga species were captured in Flora Qinghaiica. New distribution of six Saxifraga L. species in Qinghai Province was discovered based on field expedition and specimen identification, namely Saxifragaangustata , S. atuntsiensis , S.congestiflora , S. granulifera , S. heleonastes and S. pasumensis , which are neither reported in Flora Qinghaiica nor in Flora of China.
