Taxonomic and nomenclatural notes on Pedicularis (Orobanchaceae): I. One new species from northwest Yunnan, China

摘要

Pedicularis multicaulis W.B.Yu, H.Wang & D.Z.Li (series Oliganthae Prain) is a new species described and illustrated herein. This new species is endemic to northwest Yunnan and only two populations were found in Weixi county. Phylogenetic analyses support P. multicaulis as a new species, sister to P. taihaiensis Bonati and P. macilenta Franch. Morphological comparisons between P. multicaulis and P. macilenta and P. taihaiensis also support P. multicaulis as a new species to science.
