A dataset of the diversity and geographical distributions of wild Primula L.in China
Catalogue of Life serves as the background baseline information for the biota of a given natural geographic region or administrative unit.The timely updating of its dynamics is an important basis for the research,management and monitoring of biodiversity conservation.The integration and sharing of biodiversity data can provide a scientific basis for the development of related studies.Primula L.is a typical genus characterized by a broad distribution and a high degree of endemism,with diverse habitats and a complex taxon structure.An in-depth analysis of its geographical distribution pattern and characteristics can provide a foundational basis for the conservation and use of germplasm resources.With the aim of offering a reference for germplasm resource surveys and application research on seed introduction,and based on a large amount of basic data and literature,this paper adopts the taxonomic system used by Flora of China to update the list of wild species of the genus Primula L.distributed in the terrestrial area of China.In the paper,we counted their species diversity,composition and other information,and established a dataset of the diversity and geographical distributions of wild Primula L.in China.This genus predominantly thrives in the temperate and subtropical zones of the Northern Hemisphere.Its diversity center and modern distribution center are also widely distributed in the eastern Himalayas and Hengduan Mountains in broad sense,Tianshan Mountain Area,Qinba Mountain area,Wuling Mountains Area,Qinghai Tibet Plateau,Yunnan Guizhou Plateau and other high-altitude areas.Additionally,it extends to middle and lower altitude areas with prominent karst and Danxia landscapes.As of October 2022,a total of 397 species(28 varieties and 26 subspecies)of the genus Primula L.have been recorded in China,including 296 endemic species(including subspecies classification units,the same below)in China.In addition to the five administrative regions of Jiangsu,Hainan,Shanghai,Hong Kong and Macao,the distribution of wild primroses has been recorded in various provincial administrative regions in China,with Sichuan Province boasting the highest species richness and endemism at the provincial scale(177 species),followed by Yunnan Province(176 species)and the Tibet Autonomous Region(171 species).At the county scale,Shangri-La City ranks first in species richness with 62 species.
