Abstract

Most species of Paraphlomis are distributed in the south of the Yangtze River in China. In this study, a new species, P. nana, from northeast Chongqing in the north of the Yangtze River is described and illustrated. Bayesian inference and maximum likelihood analyses based on two nuclear ribosomal DNA regions (ITS and ETS) and three plastid DNA markers (rpl32-trnL, rps16, and trnL-trnF) were carried out to explore the phylogenetic position of the new species within Paraphlomis. Though the nuclear and plastid trees reveal incongruent placements of P. nana in Paraphlomis, which may be caused by chloroplast capture, a close relationship between the new species and P. albiflora is supported by molecular phylogenetic, morphological, and geographic evidence. However, the two species can be clearly distinguished from each other by the plant height and lamina and calyx morphology.
