Phylogenetic relationships in Nepeta L. (Lamiaceae) and related genera based on ITS sequence data
Abstract:The internal transcribed spacers of nuclear ribosomal DNA (nrITS) from 43 species of Nepeta and representatives of closely related genera (Lallemantia, Dracocephalum and Agastache) and outgroups (Lavandula, Stachys, Newcastelia and Prostanthera) were sequenced. Parsimony analysis indicated that Nepeta is monophyletic and composed of five major monophyletic groups, most of which comprise species belonging to more than one section in previous classifications. These five clades are composed of: (1) sect. Spartonepeta; (2) sects. Macronepeta + Spicatae; (3) sects. Nepeta + Micranthae p.p. + Oxynepeta + Schizocalyx + Macrostegiae; (4) sects. Capituliferae + Denudatae + Micranthae p.p. + Micronepeta p.p.; and (5) sect. Psilonepeta. The phylogenetic relationships among species of these groups are congruent with the distribution of some floral characters, including corolla shape, bract texture, color and pollen exine ornamentation.
