Description

Chrysosplenium ningqiangense (Saxifragaceae) is described as a new species discovered in Hanshuiyuan Forest Park, Ningqiang County, Shaanxi Province, China. Morphologically, it resembles C. serreanum, C. alternifolium and C. japonicum, but can be distinguished by its leaf shape, yellow and loose inflorescences, absence of stolons, bulbils or bulbs at the stem base, and reddish-brown seeds with a tessellate and papillate surface. Phylogenetic analyses, based on ITS and cpDNA sequences, indicate that C. ningqiangense clusters with C. hydrocotylifolium, C. guangxiense, C. macrophyllum and C. zhangjiajieense. Although these species differ in morphological characteristics, phylogenetic evidence confirms C. ningqiangense as a distinct species within the subgenus Gamosplenium.
