Core Viewpoint - A new species of the genus Primulina, named Quanzhou Primulina, has been discovered in Quanzhou County, Guangxi, by a research team from the Guangxi Institute of Botany and Guilin Tourism College, highlighting the biodiversity of the karst region in Guangxi [1] Group 1 - The new species was discovered during a field survey in March 2020, on a limestone cliff along a roadside in Quanzhou County [1] - After four years of homogeneity experiments, researchers confirmed the species' stable morphological characteristics, classifying it as a new species within the Primulina genus [1] - The species is currently only found in the crevices of vertical cliffs in Quanzhou County, with the population initially estimated at around 400 mature individuals [1] Group 2 - The population of Quanzhou Primulina decreased to fewer than 10 mature individuals due to road expansion in 2022, with no available seedlings for regeneration [1] - In spring 2025, researchers rediscovered approximately 100 mature plants about 5 kilometers from the original discovery site [1] - According to the International Union for Conservation of Nature (IUCN) classification, this species is assessed as Critically Endangered (CR) [1] Group 3 - The discovery of Quanzhou Primulina provides new evidence for the study of plant diversity in the karst region of Guangxi [1] - It also offers important clues for exploring the origin and evolutionary patterns of endemic plants in the region [1]
