摘要
2021年全球共发表维管植物新分类群2,219个,包括新亚科1个、新族7个、新亚族7个、新属68个、新亚属7个、新组15个、新亚组8个、新系10个、新种1,979个、新亚种46个、新变种59个和新变型12个;这些新分类群隶属于185科881属,兰科、菊科和茜草科是本年度最受关注的类群。2,219个维管植物新分类群由来自全球的1,942位学者发表在165个期刊和14部专著中,其中有42位作者发表了11个以上的新分类群。值得关注的是,Phytotaxa和PhytoKeys是2021年发表维管植物新分类群的主要期刊,分别发表586个和112个。本年度发表的2,096个新种及种下单元中,被子植物门1,940个、蕨类植物门147个、裸子植物门9个,其中兰科植物最多,共227个。2021年发表的新种及种下单元来自世界115个国家和地区。亚洲和南美洲是新种及种下单元发现的热点地区,分别发现837个和571个。中国、巴西和马达加斯加是2021年贡献维管植物新种及种下单元最多的前3个国家,分别发现283、269和169个。考虑到在2021年2月1日之后IPNI对2020年发表的维管植物新种增加了797个,我们估计在2022年4月16日之后,各数据库中2021年发表的新种及种下单元会增加700个左右。这将使2021年发表的新种(和种下分类群)数量增加到大约2,800个,这与2001年以来每年发表的维管植物新种数量相当。
Aims:Vascular plants provide most of the planet’s biomass.Thousands of new vascular plant species have been discovered and described every year recently.Timely analysis of the published data of new vascular plants taxa can show the research hotspots of vascular plant taxonomy in details and provide reference data for studies of related fields such as botany,ecology,and conservation science.Methods:The data were derived from the IPNI(https://www.ipni.org/),Tropicos(https://www.tropicos.org/),WCSP(https://wcsp.science.kew.org/)and The Plant List(http://www.theplantlist.org/).Statistics of new taxa of vascular plants published in 2021 were available as of April 16,2022 excluding new combinations,new statuses or new names and bryophyte data.Results:In 2021,at least 2,219 new taxa of vascular plants were described worldwide,including 1 new subfamily,7 new tribes,7 new subtribes,68 new genera,7 new subgenera,15 new sections,8 new subsections,10 new series,1,979 new species,46 new subspecies,59 new varieties,and 12 new forms.These new taxa belong to 185 families and 881 genera,among which Orchidaceae,Asteraceae and Rubiaceae had received more attentions.In 2021,2,219 new taxa of vascular plants were described worldwide in 165 journals and 14 books by 1,942 scholars,of which 42 authors have published more than 11 new taxa.Phytotaxa and PhytoKeys were the top two journals in terms of the numbers of new taxa of vascular plants published in 2021 and published 586 and 112,respectively.Among the 2,096 new species and infraspecific taxa,1,940 belonged to angiosperms,147 to pteridophytes,and only 9 to gymnosperms,among which Orchidaceae are the most,with 227.The 2,096 new species and infraspecific taxa were from 115 countries and regions in the world.Asia and South America were the hotspots of discoveries of new species and infraspecific taxa,with 837 and 571,respectively.By country,China,Brazil,and Madagascar were the top three with the most new species and infraspecific taxa discovered in 2021,with 283,269,and 169,respectiv
