Abstract

Chelonopsis is a small genus endemic to East Asia. In this study, a new species, C. guchengensis , from Nanhe National Nature Reserve, Gucheng County, Hubei Province is described and illustrated. Molecular phylogenetic analyses based on two nuclear ribosomal DNA regions (ETS and ITS) and five plastid DNA markers ( trnL intron, trnL - trnF , trnS - trnG , psbA - trnH , and rps16 ) were carried out to explore the phylogenetic position of the new species. A close relationship between the new species and C. giraldii is supported by molecular phylogenetic and morphological evidence. However, the two species can be easily distinguished from each other by mostly leaf and inflorescence morphology.
