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。

Abstract: 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.

Key words: Saxifraga, new distribution, Qinghai Province
