重楼为唇形科植物，约30种，主要分布于亚热带的中国。在这项研究中，我们首次进行了分子系统发育分析，以阐明该属内基于两个核DNA区域和四个叶绿体DNA区域的关系。我们的研究结果表明，该属不是单系种。以前在该属内描述的两个组和大部分系列也被证明是多系的。结合形态证据，我们的研究表明，小坚果形态而不是花萼形态对副瘤虫属下分类具有系统发育价值。此外，本文还记述了产于中国南部的一新种--南江青杨，并将原被视为爪哇青杨变种的冠脉青杨作为该属内的一个独特种复活。我们首次基于两个核DNA序列和四个叶绿体DNA序列对副眼虫进行了分子系统发育分析。Parphlomis和以前在该属内划定的两个组和大部分系列不是单系。小坚果形态而不是花萼形态对于副瘤属的属下分类具有系统发育价值。本文记述了采自中国南部的一新种--冠冠山新种，并确认了该种的特殊地位。在此发现的Parphlomis的系统发育骨架将作为该属未来研究的框架。
Paraphlomis is a genus of Lamiaceae with about 30 species distributed mainly in subtropical China. In this study, we carried out the first molecular phylogenetic analyses to elucidate the relationships within the genus based on two nuclear and four plastid DNA regions. Our results, which recovered a species of Matsumurella within Paraphlomis, indicate that the genus is not monophyletic. The two sections and most of the series previously described within the genus are also shown to be polyphyletic. Combining with morphological evidence, our study indicates that nutlet morphology rather than calyx morphology is of phylogenetic value for the infrageneric classification of Paraphlomis. Moreover, P. jiangyongensis, a new species from southern China, is here described, and P.coronata, formerly treated as a variety of P.javanica, is here resurrected as a distinct species within the genus. We carried out the first molecular phylogenetic analysis of Paraphlomis based on two nuclear and four plastid DNA sequences. Paraphlomis and the two sections and most of the series previously delimitated within the genus are not monophyletic. Nutlet morphology rather than calyx morphology is of phylogenetic value for the infrageneric classification of Paraphlomis. A new species, P. jiangyongensis, from southern China is described and the specific status of P. coronata is confirm. The phylogenetic backbone of Paraphlomis recovered here will serve as a framework for future studies of the genus.
