广西发现新物种全州报春苣苔

Core Viewpoint - A new species of the genus Primulina, named Quanzhou Primulina, has been discovered in Quanzhou County, Guangxi, contributing to the biodiversity research in the karst region of Guangxi [3]. Group 1 - The research team from Guangxi Institute of Botany and Guilin Tourism College discovered the new species during a joint scientific expedition in Quanzhou County [3]. - The species was first identified in March 2020 on a limestone cliff, and after four years of homogeneity experiments, it was confirmed as a new species of the Primulina genus [3]. - The species is currently only found in the vertical crevices of cliffs in Quanzhou County, with the name derived from the location of its type specimen [3]. Group 2 - Initially, around 400 mature individuals were found densely distributed on the cliff, but environmental changes led to a decline in the population to fewer than 10 individuals by 2022, with no seedlings available for regeneration [3]. - In spring 2025, approximately 100 mature plants were rediscovered about 5 kilometers from the original location [3]. - According to the International Union for Conservation of Nature (IUCN) classification, this species is assessed as Critically Endangered (CR) [3]. Group 3 - The discovery of Quanzhou Primulina provides new evidence for the study of plant diversity in the karst region of Guangxi and offers important clues for exploring the origin and evolutionary patterns of endemic plants in the area [3].
