Molecular Phylogeny and taxonomy of East Asiatic Salvia (Lamiaceae, Nepetoideae).

Salvia, consisting of about 1,000 species, is the largest genus within Lamiaceae. About 100 species of Salvia are native to East Asia (EA), making EA one of the three major biodiversity centers of the genus. Salvia is a widely used across EA both horticulturally and medicinally. Although previous studies have suggested that EA Salvia are monophyletic, relationships within this lineage remain unclear. Phylogenetic relationships inferred from two nuclear ribosomal (nrDNA; ITS and ETS) and four chloroplast (psbA-trnH, ycf1-rps15, trnL-trnF, and rbcL) markers strongly support the monophyly of EA Salvia. We identified eight major clades. Subclade A, comprising two limestone endemics (S. sonchifolia and S. petrophila), is sister to the remainder of EA Salvia. As a result of our analyses we propose a new classification system matching both molecular phylogenetic and morphological evidence, and recognize EA Salvia clade as a subgenus (Glutinaria) and subdivide the subgenus into eight sections.
