Abstract

We describe here a rare, critically endangered new species of the genus Cheniella from Guangdong province of southern China. Cheniella tsoongii is morphologically similar to C. corymbosa, and can be distinguished by having a combination of deeply-bilobed hairy leaves, white flowers, shorter hypanthia, yellow anthers, and densely ferruginous-tomentose inflorescence rachides, pedicles and hypanthia. We suggest assessing the conservation status of the species as Critically Endangered (CR) as it possesses an extremely high risk of extinction based on the rapid population declines during the last century and, only no more than 10 individuals remain in an environmentally unprotected area now. Urgent conservation studies and actions are necessary to prevent the extinction of this species.

中国南方的一个稀有、极度濒危的新物种：Cheniella tsoongii (Leguminosae: Cercidoideae)

我们在本文中描述了产自中国南方广东省的一种珍稀、极度濒危的车前草属新物种。从形态上看，陈皮草属（Cheniella tsoongii）与陈皮草属（C. corymbosa）相似，但其叶片深裂有毛，花白色，托杯较短，花药黄色，花序轴、花梗和托杯密被铁锈色绒毛。我们建议将该物种的保护状态评估为极度濒危（CR），因为在上个世纪，该物种的种群数量迅速减少，目前在一个未受保护的地区仅存不超过 10 个个体，灭绝风险极高。为防止该物种灭绝，有必要开展紧急保护研究并采取行动。

期刊介绍： Phytotaxa is a peer-reviewed, international journal for rapid publication of high quality papers on any aspect of systematic and taxonomic botany, with a preference for large taxonomic works such as monographs, floras, revisions and evolutionary studies and descriptions of new taxa. Phytotaxa covers all groups covered by the International Code of Nomenclature foralgae, fungi, and plants ICNafp (fungi, lichens, algae, diatoms, mosses, liverworts, hornworts, and vascular plants), both living and fossil. Phytotaxa was founded in 2009 as botanical sister journal to Zootaxa. It has a large editorial board, who are running this journal on a voluntary basis, and it is published by Magnolia Press (Auckland , New Zealand). It is also indexed by SCIE, JCR and Biosis. All types of taxonomic, floristic and phytogeographic papers are considered, including theoretical papers and methodology, systematics and phylogeny, monographs, revisions and reviews, catalogues, biographies and bibliographies, history of botanical explorations, identification guides, floras, analyses of characters, phylogenetic studies and phytogeography, descriptions of taxa, typification and nomenclatural papers. Monographs and other long manuscripts (of 60 printed pages or more) can be published as books, which will receive an ISBN number as well as being part of the Phytotaxa series.
