A new species and a new record of Phlomoides (Lamiaceae) from Xizang, China.

ABSTRACT

Phlomoidesbomiensis, a new species in Bomi County, Xizang, China, was described and illustrated. In addition, Phlomoideslongidentata, previously only known from Nepal and Bhutan, is newly recorded from Dingri County, Xizang, China. The phylogenetic placement of both species within the genus was analysed using nine plastid DNA markers (atpB-rbcL, psbA-trnH, rpl16, rpl32-trnL, rps16, trnK, trnL-trnF, trnS-trnG, trnT-trnL). Both species have brown-black trichomes inside the upper corolla lip and nested within the same subclade of Clade II. A diagnostic key to the Phlomoides species belonging to this subclade is provided.
