Abstract
Pternopetalum wulingense (Apiaceae) is described as a new species from the Wuling Mountains in Guizhou Province and Chongqing Municipality, China. Both phylogenetic analyses and diagnostic morphological traits support its placement within Pternopetalum and confirm its distinction from close relatives. It closely resembles P. trichomanifolium in having finely dissected 3–4-pinnate basal leaves and a preference for moist habitats, but differs in having a rhombic leaf blade outline, ultimate segments of uniform width and oblong-ovoid fruits with both mericarps fully developed.
