Pternopetalum wulingense (Apiaceae), a new species from the Wuling Mountains, China

<i>Pternopetalum wulingense</i> (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 <i>Pternopetalum</i> and confirm its distinction from close relatives. It closely resembles <i>P. trichomanifolium</i> 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.
