Resurrection of Pleurospermum lecomteanum H.Wolff (Apiaceae) based on molecular and morphological evidence

Abstract

The taxonomic placement of Pleurospermum lecomteanum, previously synonymized with Pleurospermum wilsonii, was carefully examined using herbarium specimens and molecular evidence. The results showed that Pleurospermum lecomteanum is distinguished from P. wilsonii by several morphological characters. Its phylogenetic position is separate from P. wilsonii in the ML tree. Therefore, Pleurospermum lecomteanum should be restored as a distinct species.
