摘要:

通过查阅233种期刊和新出版的相关书籍, 并对各种网络数据库进行交叉检索和系统梳理, 共检索到4部书籍和63种刊物中发表的419篇文章包含中国植物新分类群、新组合、新名称、异名、模式化、名称更正以及国家级新记录、排除中国分布、物种再次发现等与中国植物物种编目相关的内容。数据显示, 2023年中国共发表高等植物新属14个, 新种(含新杂交种) 241个, 新种下分类群13个, 新高阶等级13个(新亚科7个, 新超族4个, 新族2个), 新亚属2个, 新组6个; 发表新组合(等级) 185个(种级组合173个, 种下等级组合12个), 新名称15个; 发表国家级新记录科1个、属5个、种82个、种下等级4个; 将86个名称处理为58个名称的异名; 还新发现多年未曾发现的物种5个, 排除物种分布1个。新发表的物种中, 有苔藓植物9种、蕨类植物22种及1个种下等级、裸子植物1个新杂交种、被子植物209种(含2个杂交种)及12个种下等级。这些新种中, 有116个在发表的同时提供了详细的分子证据, 62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、广西和四川等西南4省区发表新种最多, 占全国新种发表总数的2/3; 墨脱县是新种发现数量最多的县级行政单位, 发表了14个新种和14个新记录种; 盈江县是国家级新记录种发现最多的县级行政单位, 发现了21种国家级新记录植物。2023年中国高等植物净新增262个分类群种, 占全国高等植物总数的0.56%, 200个高等植物名称发生变动, 占全国总数的0.43%。多项指标显示, 中国植物的新分类群发表和名称变化的数量开始呈现波动下降的趋势, 但是否进入下降通道还需要进一步的数据跟踪和分析。

Abstract

Aims: Since 2020, the average annual number of changes in plant names in China has accounted for roughly 1.5% of all changes. Although these plant name changes are not large, cumulative changes over time should not be ignored. Indeed, it is necessary to annually compile information on new taxa, records, and name changes to Chinese plants to integrate these changes into the Catalogue of Life China in a timely manner to facilitate more accurate references for academia and research.

Methods: We collected data on newly discovered taxa and name changes for Chinese higher plants by reviewing 233 journals and related monographs, supplemented by cross-referencing and systematic review using various online databases to ensure the accuracy and comprehensiveness of the compiled information. This compilation involved 419 articles from 63 journals and 4 monographs, and mainly focused on the new taxa and nomenclatural changes in higher plants in 2023.

Results: In 2023, China reported several new taxonomic findings, including 14 genera, 241 species (including new hybrid species), 13 infraspecific taxa, 13 higher taxa (including 7 subfamilies, 4 supertribes, and 2 tribes), 2 subgenera, and 6 sections in higher plants. Additionally, 185 novel combinations (173 at the species level and 12 at the infraspecific level) and 15 new names were published. At the national level, 1 new record family, 5 new record genus, 82 new record species, and 4 new record infraspecies were recently documented. Furthermore, 86 names were synonymized into 58 names. Five species that had not been observed for many years were rediscovered, and one species distribution was excluded. Among the newly published species, there were 9 bryophytes, 23 pteridophytes (including 1 infraspecific taxon), 1 gymnosperm hybrid, and 221 angiosperms (including 2 hybrids and 12 infraspecific taxa). Detailed molecular evidence was provided for 116 of these novel species at the time of publication that account for 46% of all new species. Additionally, 62 species were assessed as threatened according to IUCN standards upon their publication, which represents 24% of all new species. By location, the four southwestern provinces, i.e. Yunnan, Xizang, Guangxi, and Sichuan, published the highest number of new species and accounted for two-thirds of the total new species reported nationwide. In particular, Mêdog County recorded the highest number of new species among county-level administrative units, with 14 new species and records. Likewise, Yingjiang County reported the highest number of national new records, with 21 new plant records documented.

Conclusion: In 2023, China witnessed a net increase of 262 new taxa of higher plants that accounts for roughly 0.56% of all Chinese higher plant species. In addition, 200 names underwent changes, which accounts for 0.43%. These changes represented 0.99% of all Chinese higher plant names modified in 2023 and encompasses both species additions and nomenclature treatments. Multiple indicators suggest that the number of newly published plant taxa and name changes in China are beginning to show a downward trend. However, data tracking and analysis are needed to determine if this decline will continue in the future.
