摘　　要：2021年中国共发表高等植物新分类群342个,其中新科1个,新属11个,新种289个,新亚种3个,新变种18个,新变型20个。新发表的物种分别属于苔类植物门(5个新种)、藓类植物门(4个新种)、石松门(3个新种)、蕨类植物门(22个新种)、裸子植物门(2个新种)、被子植物门(253个新种)。其中111个新种同时提供了详细的分子证据,76个在发表时就依据IUCN标准被评估处于受威胁的状态。云南、西藏、四川和广西等西南4省区发表的新种最多,共占全国新种发表总数的63.3%;新种发现密度最高的省级行政单位是台湾、海南、云南、浙江和广东等省区。2021年中国共发表植物新组合(等级)134个,新名称9个;发表国家级新记录62个;将92个名称处理为62个名称的异名;对7个名称进行了应用订正;重新承认了2个属和10个物种;新指定后选(新)模式物种49个;还新发现多年未曾发现的物种9个,排除物种分布7个。2021年中国高等植物净新增364个分类群,占全国植物总数的0.98%,230个高等植物名称发生变动,占全国植物总数的0.62%。Aim:Each year,more than 220 species from China are documented as new species.However,much of this information has yet to be updated in international databases.Here we aimed to update the annual report with the newly discovered taxa and name changes of existing plants in China from the year 2021.Methods:Information on newly discovered taxa and name changes for Chinese higher plants were collected by reviewing 222 journals and monographs,where 380 articles published in 62 journals and 2 monographs concerning the new taxa and nomenclatural changes of higher plants published in 2021.For each species,we compiled the scientific name,author,location,type specimen,and other relevant information.Results:In 2021,a total of 342 new taxa of higher plants from China were reported,including 1 new family,11 new genera,289 new species,3 new subspecies,18 new varieties,and 20 new forms.The newly described species belong to the Marchantiophyta(5 species),Bryophyta(4 species),Lycopodiophyta(3 species),Pteridophyta(22 species),Gymnospermae(2 species),and Magnoliophyta(253 species).A total of 111 new species had been published with detailed molecular evidence,76 of which were considered threatened species according to IUCN standards.Four provinces in southwestern China,including Yunnan,Xizang,Sichuan,and Guangxi,were the sources of the majority of the discoveries.The species found in these regions account for 63.3%of the total reports collected in our review.Taiwan,Hainan,Yunnan,Zhejiang,and Guangdong have the highest densities of newly discovered species.Additionally,we identified 134 new combinations and new rank names.We identified 9 replacement names transferred from other species distributed across China.Sixty-two plants were reported as novel to China,92 names were given as synonyms of 62 taxa,7 names were revised,and 2 genera and 10 species were re-recognized.Further,49 names were designated lectotypes or neotypes,9 species were rediscovered,and 7 were considered no longer present in China.Conclusion:In 2021,a net increase of
