广西发现极度濒危新物种全州报春苣苔

Core Viewpoint - A new species of the genus Primulina, named "Quanzhou Primulina," has been discovered by a research team from Guangxi Institute of Botany and Guilin Tourism College in Quanzhou County, Guangxi, with findings published in the international journal Phytotaxa [1][3]. Group 1 - The new species was initially discovered during a field survey in March 2020 on a limestone cliff in Quanzhou County, and after four years of homogeneity garden experiments, it was confirmed as a new species of the genus Primulina [3]. - The species is currently only found in the vertical rock crevices of Quanzhou County, with the type specimen collected from this area, leading to its naming as "Quanzhou Primulina" [3]. - Approximately 400 mature individuals were densely distributed at the initial discovery site, but environmental changes caused the population to decline to fewer than 10 individuals by 2022, with no available seedlings for regeneration [5]. Group 2 - In spring 2025, researchers rediscovered about 100 mature plants approximately 5 kilometers from the original discovery site [5]. - According to the International Union for Conservation of Nature (IUCN) classification, this species is assessed as Critically Endangered (CR) [5]. - 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 [5].
