中文摘要：

类 Lamiophlomis 和 Paraphlomis 原来根据特别词法特征与类 Phlomis s.l 被分开。然而，他们的关系是高度有争议的，作为由文学证实了。在现在的纸， Lamiophlomis， Paraphlomis，和他们的相关的类的系统的位置基于原子内部抄录分隔符被估计(它的) 并且用最大的吝啬(MP ) 和贝叶斯的方法的叶绿体 rpl16 和 trnL-F 顺序数据。总共，代表内集团和外集团的六个类的 24 种类被取样。分开、联合的顺序数据的分析被进行解决这些类的系统的关系。结果表明 Lamiophlomis 在 Phlomis 派别以内被嵌套。Phlomoides 和它的通用地位没被支持。与在派别的 Lamiophlomis rotata 的包括。Phlomoides，节 Phlomis 和 Phlomis 的 Phlomoides 作为单音被解决门。Paraphlomis 作为一个独立的类被支持。然而，决定它的 monophyly 在 MP 和贝叶斯的分析之间冲突了，为花费的采样和进一步的证据建议需要。

英文摘要：

Genera Lamiophlomis and Paraphlomis were originally separated from genus Phlomis s.1. on the basis of particular morphological characteristics. However, their relationship was highly contentious, as evidenced by the literature. In the present paper, the systematic positions of Lamiophlomis, Paraphlomis, and their related genera were assessed based on nuclear internal transcribed spacer （ITS） and chloroplast rpl16 and trnL-F sequence data using maximum parsimony （MP） and Bayesian methods. and outgroup were sampled. Analyses of both separate In total, 24 species representing six genera of the ingroup and combined sequence data were conducted to resolve the systematic relationships of these genera. The results reveal that Lamiophlomis is nested within Phlomis sect. Phlomoides and its generic status is not supported. With the inclusion ofLamiophlomis rotata in sect. Phlomoides, sections Phlomis and Phlomoides of Phlomis were resolved as monophyletic. Paraphlomis was supported as an independent genus. However, the resolution of its monophyly conflicted between MP and Bayesian analyses, suggesting the need for expended sampling and further evidence.
