Lysimachia danxiashanensis, a new species of Primulaceae from Guangdong, China

A new species of Primulaceae, Lysimachia danxiashanensis, has been discovered in the unique Danxia landscape of Guangdong Province, China. This endemic plant is morphologically distinct from its closest relatives, characterized by purplish-red plants, wingless petioles, an orange glandular calyx, and a serrated corolla margin with orange-red glandular punctates. Phylogenetic analysis using ITS and rbcL sequences confirmed its status as a distinct clade within Lysimachia subgen. Lysimachia sect. Nummularia. The species is classified as Endangered (EN) under the IUCN Red List, highlighting the urgent need for conservation efforts in its native habitat.
