Abstract

Peucedanum huangshanense, a new species discovered in Anhui, China, is illustrated and described. Detailed morphological comparisons have showed that it is similar to P. praeruptorum but differs from the latter by having larger compound umbels (5–14 cm across), rays up to 25, and long-ovoid mericarps with lateral ribs narrowly winged. To explore the phylogenetic position of this species, nuclear ribosomal DNA internal transcribed spacer (ITS) region was sequenced for P. huangshanense and P. praeruptorum collected in different places. The morphological and molecular evidences support the hypothesis that P. huangshanense is a new distinct species.
