鼠尾草亚属（Salvia subgenus Calocelaceae）是唇形科（Lamiaceae）鼠尾草属（Salvia）植物中重要的经济和民族药用植物，约有500余种。虽然它被认为是单系的，但自1939年建立91个分类组以来，还没有得到全面系统的研究。对73个组的代表类群进行了系统发育分析，并利用叶绿体（psbA-trnH）和核核糖体DNA（internal transcribed spacer）对主要类群进行了鉴定。系统发育分析的组合数据集建立单系的七个组（Blakea，Corrugelae，Erythrostachys，Hastatae，Incarnatae，Microstrapace和Sigmoideae）和四个主要谱系（S。axillaris，“Hastatae进化枝”，“Uligarum进化枝”，和“core Calocarus ace”）。我们的研究结果不支持跨越两个或更多多样性中心的部分;相反，支持的关系表现出显着的地理结构。墨西哥被支持作为Calocalpace的地理起源，并不超过7个分散到南美洲的事件需要考虑到目前的间断分布。
Salvia subgenus Calosphace (Lamiaceae) is economically and ethnomedicinally significant and comprised of more than 500 species. Although strongly supported as monophyletic, it has received no comprehensive systematic research since the initial establishment of 91 taxonomic sections in 1939. Representative taxa of 73 sections of Calosphace were sampled to investigate the phylogenetic relationships and identify major lineages using chloroplast (intergenic spacer psbA-trnH) and nuclear ribosomal DNA (internal transcribed spacer). Phylogenetic analysis of the combined data sets established monophyly of seven sections (Blakea, Corrugatae, Erythrostachys, Hastatae, Incarnatae, Microsphace, and Sigmoideae) and four major lineages (S. axillaris, "Hastatae clade", "Uliginosae clade", and "core Calosphace"). Sections spanning two or more centers of diversity are not supported by our results; rather, supported relationships exhibit significant geographic structure. Mexico is supported as the geographic origin of Calosphace, and no more than seven dispersal events to South America are required to account for current disjunct distributions.
