Phylogeny of the subtribe Hyptidinae (Lamiaceae tribe Ocimeae) as inferred from nuclear and plastid DNA

Abstract Phylogenetic analyses of the subtribe Hyptidinae (Lamiaceae) based on nuclear ITS and ETS, and plastid trnL‐F, trnS‐G, trnD‐T , and matK are presented. The analysis of the ITS dataset included 218 specimens representing 180 species of Hyptidinae. This analysis was used to select a smaller representative sample of 69 species of Hyptidinae for further analysis based on all above regions. The monophyly of Hyptidinae and almost all genera is well‐supported, with noticeable paraphyly of Hyptis which is ancestor of all remaining genera of Hyptidinae. Eriope is monophyletic with the exclusion of E. simplex , while Hypenia represents a monophyletic group excluding H. vitifolia. Hyptis eximia was shown to be associated with Hyptidendron , and Peltodon is embedded within the Hyptis s.str. clade. Internal relationships within Hyptis s.str. were not completely resolved; a preliminary discussion on the taxonomy treatment of the complex and the subdivision of Hyptis are presented.
