Abstract

Hedyotis taishanensis is described as a new species from China. It is similar to H. acutangula, but obviously differs in unbranched herbal stems with slightly winged ridges, petiolated leaves, abaxially pubescent stipules, terminal pleiochasium inflorescence. The phylogenetic analysis from nuclear ITS and plastid petD sequences of 27 taxa revealed that H. taishanensis was an independent lineage but closely related to the clade including the sympatric species endemic to the Pearl River Delta, Guangdong, China. It was evaluated as Least Concern according to the IUCN Red List Categories and Criteria.
