Abstract: GeneraLamiophlomis and Paraphlomis were originally separated from genus Phlomis s.l. according to some particular morphological characters. However, their relationship was highly controversial as referred to diverse literature and studies. In this paper, the systematic positions of Lamiophlomis, Paraphlomis and their related genera were assessed based on nuclear ITS and chloroplast rpl16, trnL-F sequences data using Maximum Parsimony and Bayesian methods. Totally 24 species representing 6 genera of ingroup and outgroup were sampled in this study. Analyses of both separate and combined sequence data were conducted in resolving the systematic relationships of these genera. Our results revealed that Lamiophlomis was nested within Phlomis sect. Phlomoides, and its generic status was not supported. With the inclusion of Lamiophlomis rotata in sect. Phlomoides, sections Phlomis and Phlomoides of Phlomis were resolved as monophyletic respectively. Paraphlomis was supported as an independent genus. However, the resolution of its monophyly conflicted between MP and Bayesian analyses suggesting the necessity of expended sampling and further evidence.

Key words: ITS, Lamiophlomis, Paraphlomis, rpl16, systematic position, trnL-F.
