摘要

我们描述并说明了马拉维南部地区的一个新种 Tragia grandistipularis（大戟科），它的大托叶很容易区分。我们修改了《植物志》（Flora Zambesiaca）中该属的检索表，以适应该新种。该新种仅从一个濒危栖息地的单一种群中获知。根据其有限的已知分布以及该栖息地面临的威胁，我们按照世界自然保护联盟红色名录的类别和准则，将其暂时评估为极危（CR），标准为 B2ab(i,ii,iii,v)。我们建议开展进一步调查，以更好地了解这个新物种的生态和分布情况。

Tragia grandistipularis (Euphorbiaceae), a new species from Malawi

We describe and illustrate Tragia grandistipularis (Euphorbiaceae), a new species from the Southern Region of Malawi, which is easily distinguished by its large stipules. We amend the key to the genus in Flora Zambesiaca to accommodate the new species. The new species is only known from a single population in a threatened habitat. Based on its limited known distribution and the threats to this habitat, we provisionally assess it as Critically Endangered (CR) with criteria B2ab(i,ii,iii,v) following the IUCN Red List categories and guidelines. We recommend further surveys to better understand the ecology and distribution of this new species.

期刊介绍： Kew Bulletin is an international peer-reviewed journal for the taxonomy, systematics and conservation of vascular plants and fungi. Papers on conservation, evolution, palynology, cytology, anatomy, biogeography and phytochemistry are considered, where relevant to taxonomy and systematics. Review papers on topics appropriate to the journal are invited. The journal is richly illustrated with line drawings and photographs, and also features a Book Review and Notices section. Four parts (c. 640 pp) are published each year.
