Abstract

We describe, discuss, and illustrate Dichorisandra flesheri, a new species endemic to the Atlantic Forest in southern Bahia state, Brazil, based on field and herbarium studies. The species was assessed as ‘Endangered’, especially for its restricted distribution and differs strongly from other species of the genus by a set of characters that includes stem, leaves and inflorescence with a hairy indument, a pendulous inflorescence and flowers with six stamens, anthers slightly sagittate at base, yellowish, opening introrsely with longitudinal slits, but functionally poricidal. Discussion of relevant characters, comparisons with similar species, descriptions, distribution map of the species, information on conservation status and illustrations are provided.

Dichorisandra flesheri（Commelinaceae），巴西南巴伊亚的一个娇嫩新种

Dichorisandra flesheri是巴西巴伊亚州南部大西洋森林特有的一个新物种，我们基于野外和标本馆研究对其进行了描述、讨论和说明。该物种被评定为 "濒危物种"，特别是因为其分布范围有限，并且与该属的其他物种有很大不同，其特征包括茎、叶和花序有毛状的毛被，花序下垂，花有六枚雄蕊，花药基部略呈箭头形，淡黄色，内开有纵裂，但功能上有孔隙。本报告提供了相关特征的讨论、与相似物种的比较、描述、物种分布图、保护状况信息和插图。

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.
