摘要:

中国植物物种名称随着新分类群的发表和新记录的发现而增加, 随着新分类处理带来的组合、替代和归并而变化, 随着名称修订和错误订正而改正, 随着中国产地被排除而减少。这些资料都零散地存在于各种出版物中, 需要及时整理并在具体类群专家指导下尽快收录于中国生物物种名录之中。本文通过广泛的文献检索和数据校正, 筛选出2022年出版的1部书籍和62种刊物中发表的403篇文章, 对其中与中国植物物种编目相关的内容进行了标准化, 并将标准化的数据以Excel文件的形式共享。排除异常数据后, 2022年中国境内共发表植物新属12个, 新种286个, 新种下类群20个, 新记录属6个, 新记录种及种下等级57个, 重新发现多年未见物种4个, 排除中国分布物种6个。新发表的物种分别属于被子植物(262种及种下等级)、裸子植物(1种)、石松类和蕨类植物(28种)、苔藓植物(15种及种下等级), 其中155个类群发表时提供了除形态学信息之外的分子系统学、染色体、微形态、基因组等方面的证据, 综合性证据的使用率超过50%, 有92种在发表时就依据IUCN标准被评估处于受威胁状态。云南、四川、西藏、广西、贵州等西南省区发表和发现的新分类群和新记录数量最多, 墨脱是全国新分类群发现最多的县。2022年中国还发表新组合(等级)名称122个, 新名称11个, 有103个植物名称被处理为76个物种的异名, 重新承认4个物种。2022年高等植物净增加346个分类群, 占全国高等植物总量的0.89%, 240个高等植物名称发生变动, 占全国高等植物总数的0.62%, 总体植物名称变化率为1.5%。

Abstract

Aim: Plant species names undergo revisions and changes in response to deepening taxonomic research deepens and new discoveries. These valuable diverse pieces of information are scattered across various publications, requires necessitate timely consolidation into the Species Catalogue of China, under the guidance of taxonomic experts. To address this requirement, it is necessary to create a dataset containing information on new taxa, name changes, and the latest statuses of plants in China.

Methods: We collected data on newly discovered taxa and name changes for Chinese higher plants by reviewing 228 journals and monographs. This compilation involved 403 articles from 62 journals and 1 monograph, focusing on the new taxa and nomenclatural changes of higher plants in 2022.

Results: In 2022, China reported a total of 318 new taxa of higher plants, encompassing 12 new genera, 286 new species, 3 new subspecies, 10 new varieties, and 7 new forms. The recently described species fall into bryophytes (15 taxa), pteridophytes (28 species), gymnosperm (1 species), and angiosperms (362 taxa). Notably, 155 newly identified species have been published with detailed evidence covering molecular systematics, chromosomes, micromorphology, genome, etc. Among these, 92 species were considered as threatened according to IUCN standards. The majority of these discoveries originate from five southwestern provinces in China, namely Yunnan, Sichuan, Xizang, Guangxi, and Guizhou. Medog, a county-level unit, recorded the highest number of newly discovered species in 2022. Furthermore, 122 new combinations and 11 replacement names were transferred from other species. Additionally, 103 names were designated as synonyms for 76 taxa, while 4 names were re-accepted.

Conclusion: In 2022, China witnessed a net increase of 346 new taxa of higher plants, accounting for 0.89% of the total Chinese plant species. Additionally, 240 names of higher plants underwent changes, accounting for 0.62% of the total. These changes represented 1.5% of all Chinese plant names modified in 2022, encompassing both species additions and nomenclature treatments.
