Abstract

Lysimachia danxiashanensis, a new Primulaceae species, endemic to the Danxia landscape in Guangdong Province, China, is described and illustrated. This new species is morphologically similar to L. pseudohenryi, L. phyllocephala, L. congestiflora and L. kwangtungensis, but it differs from the similar species by its purplish-red plants, petiole without wings, calyx with orange glandular and the corolla margin serrated on upper half with orange-red glandular punctates. This new species belongs to Lysimachia subgen. Lysimachia sect. Nummularia. Phylogenetic analysis confirmed that L. danxiashanensis is a distinct clade, based on the combined data of ITS and rbcL sequences. The conservation status of the new species was evaluated as Endangered (EN) according to IUCN Red List Categories and Criteria. [ABSTRACT FROM AUTHOR]
