Abstract

Euploca wightiana P.Javad & Ancy sp. nov., a new species of the family Heliotropiaceae is described from the Coimbatore district of South India. Morphologically, it is close to Euploca marifolia but differs in having erect (versus prostrate) habit, stem woody throughout (versus stem woody only at base) with dense hairs (versus sparsely hairy), oblong leaves (versus lanceolate) with obtuse apex (versus acute), inflorescence with distantly placed flowers (versus inflorescence with closely placed flowers), a 0.6 mm long cylindrical style (versus style less than 0.3 mm long), a unifid, capitate stigma (versus bifid, conical) and densely hirsute nutlets (versus minutely hairy or glabrous). Detailed descriptions, photo plates, and distribution maps are provided. Differences from morphologically allied congeners are discussed. The status of the new species is provisionally assessed here as ‘critically endangered (CR)' following the IUCN red list categories and criteria.

Euploca wightiana(Heliotropiaceae),南印度的一个新种
Euploca wightiana P.Javad & Ancy sp.nov.是 Heliotropiaceae 科的一个新种,产于南印度哥印拜陀地区。从形态上看,它与 Euploca marifolia 很相似,但不同之处在于其习性为直立(而非匍匐),茎全木质化(而非茎仅基部木质化),有浓密的毛(而非稀疏的毛),叶长圆形(而非披针形),先端钝(而非锐尖),花序上花的位置较远(而非花序上花的位置较近),花柱长 0.6 毫米长的圆柱形花柱(而花柱不到 0.3 毫米长),单裂、头状的柱头(而柱头双裂、圆锥形)和密被长硬毛的小坚果(而小坚果微有毛或无毛)。本报告提供了详细描述、照片和分布图。讨论了与形态上的同属植物的差异。根据世界自然保护联盟(IUCN)红色名录的分类和标准,该新物种的地位暂定为 "极度濒危(CR)"。

期刊介绍: Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
