General report on new taxa of vascular plants in Guangxi
摘要
Abstract
The species number of vascular plants in Guangxi is increasing and the diversity is more rich with the deepening of field investigation and research.In the last 25 years,data about new taxa of vascular plants in Guangxi(new species,new varieties,new subspecies and new variants,etc.)have been scattered in various publications.It is necessary to collate and make statistics in time.Thus,the species composition,distribution,distinctive taxa and conservation status can be fully displayed,and provided an important resource guarantee for the protection and sustainable utilization of plant diversity in Guangxi.Based on extensive literature review and data proofreading,the statistical results are as follows:(1)A total of 683 new taxa of vascular plants belonging to 85 families and 206 genera in Guangxi have been reported from 2000 to 2024.The dominant families and genera were Gesneriaceae,Begoniaceae,Asparagaceae,Urticaceae,Primulina,Begonia,Aspidistra and Elatostema.(2)The new taxa are highly rare and endemic,including 70.42％of limestone specific,85.51％of Guangxi endemic,49.93％of threatened,22 species under state key protected protection,and 24 species under Guangxi key protected protection.(3)Karst areas rich in biodiversity are the main distribution,and more new taxa are reported in non-protected areas than in protected areas.Jingxi City is the county-level region where the most new taxa have been reported.(4)The research institutes are the main contributors to the new taxa in Guangxi,and led by Guangxi Institute of Botany.The discovery and report of these new plant taxa are the important embodiment of the rich plant diversity and the improvement of ecological environment quality in Guangxi.关键词
