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].

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]
