Abstract

Abstract:

Aims: Several thousands of new vascular plant taxa have been discovered and described every year in the past 20 years. Timely analysis of the published data of new vascular plant 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 of global new taxa of vascular plants were derived from the IPNI (https://www.ipni.org/), Tropicos (https://www.tropicos.org/), WCSP (https://wcsp.science.kew.org/), and WFO (http://www.worldfloraonline.org/). Statistics of new taxa of vascular plants published in 2022 were available as of April 17, 2023 excluding new combinations, new statuses or new names and bryophyte data.

Results: In 2022, at least 2,482 new taxa of vascular plants (based on data available as of April 17, 2023; the final number will increase ca. 20% to ca. 3,000) were described worldwide, including 3 new subfamily, 19 new tribes, 11 new subtribes, 80 new genera, 7 new subgenera, 1 new supersection, 51 new sections, 16 new subsections, 4 new series, 2,160 new species, 44 new subspecies, 65 new varieties, and 21 new forms. These new taxa belong to 174 families and 905 genera, among which Orchidaceae, Araceae, and Asteraceae had received more attentions. The 2,482 new taxa of vascular plants were described worldwide in 166 journals and 15 books by 2,016 scholars, of which 53 authors published more than 10 new taxa. The number of new taxa described in 2022 was about 12% increase in comparison with that in 2021. Phytotaxa and PhytoKeys were the top two journals in terms of the numbers of new taxa of vascular plants published in 2022 and published 556 and 193 new taxa, respectively. Among the 2,290 new species and infraspecific taxa, 2,195 belonged to angiosperms, 86 to lycophytes and pteridophytes, and only 9 to gymnosperms, among which Orchidaceae were the most, with 268. The 2,290 new species and infraspecific taxa were from 110 countries and regions. Asia and South America were the hotspots of discoveries of new species and infraspecific taxa, with 874 and 577, respectively. By country, China, Brazil, and Australia were the top three with the most new species and infraspecific taxa discovered in 2022, with 337, 256, and 130, respectively.
