鼠尾草属是唇形科第一大属，共约1000种，具有中南美洲、地中海—西亚、东亚三个多样性分布中心。泛喜马拉雅地区是地中海—西亚和东亚两个分布中心的交汇地带，该地区鼠尾草属植物分化极为强烈，物种的划分与界定较为困难。该属植物具有重要的药用和观赏价值。目前，泛喜马拉雅地区的研究资料比较零散，且因年代久远和编研水平参差不齐而不能真实地反映该地区鼠尾草属的物种多样性。本研究拟通过查阅世界各主要标本馆的馆藏标本，加强该地区的野外调查，结合孢粉学、种子形态学及细胞学方面的研究资料，对该地区鼠尾草属植物进行全面地分类修订，拟澄清该地区鼠尾草属的物种多样性，为合理开发利用该地区鼠尾草资源，探讨地中海—西亚和东亚两个分布中心之间的区系关系提供理论依据。

Salvia is the largest genus of Lamiaceae with an estimated 1000 species, and three diversity centers have been recognized (Central and South America, Mediterranean-western Asia, and eastern Asia). Salvia species radiates extensively in Pan-Himalayas, where is the junction of the last two diversity centers, and species delimitation for this region is relatively difficult. Some species of the genus have important medicinal and ornamental values. Existing literatures are scattered, uneven in research level, and have been written for a quite long time so that they can’t present true species diversity of Salvia from Pan-Himalayas. On the basis of extensive field investigation and specimen study, as well as research data from micromorphology of pollen, nutlet and chromosome, taxonomic revision of Salvia from Pan-Himalayas will be conducted. This study will clarify biodiversity of Salvia from this region, which could provide more information for utilizing the resource of Salvia and discussing floristic relationships between Mediterranean-western Asia and eastern Asia centers.
