摘要

本文描述了中国四川的一新种微趾纳瓦乌山（Microtoenawawushanensis）。该新种与mmoupinensis和mprainiana亲缘关系密切，但在叶片、花萼和苞片形态上与两者有明显差异。进一步区分它的高度可变和不稳定的花萼齿比（1.36-2.13），在下部花冠和花丝上有红色标记的侧裂片，在上部和基部都是具半倒齿的，在中部有几乎不可见的毛。基于叶绿体基因组的81个编码区进行的系统发育分析表明，瓦乌山m.s awwushanensis属于Delavayana节，是m.s urticifolia, m.p ainiana和m.s megacalyx组成的分支的姐妹。

Microtoenawawushanensis (Lamiaceae, Lamioideae): A new species from Sichuan, China.

Microtoenawawushanensis, a new species from Sichuan, China, is described and illustrated here. The new species is closely related to M.moupinensis and M.prainiana, but differs distinctly from both in leaf, calyx and bract morphology. It is further distinguished by its highly variable and unstable calyx tooth ratio (1.36-2.13), red-marked lateral lobes on the lower corolla and filaments that are barbate at both the upper and basal parts, with nearly imperceptible hairs in the middle section. Phylogenetic analyses, based on 81 coding regions of the chloroplast genome, suggest that M.wawushanensis belongs to sect. Delavayana and is sister to a clade formed by M.urticifolia, M.prainiana and M.megacalyx.
