Abstract

Didymocarpus pingyuanensis, endemic to the Danxia landscape in Pingyuan County, Guangdong, China, is described and illustrated here. This species can be distinguished from other members of Didymocarpus sect. Heteroboea by its calyx deeply 5-lobed to about three quarters of its length. The phylogenetic position of the new species within Didymocarpus was examined using nuclear ribosomal internal transcribed spacer (ITS) sequences. Based on phylogenetics analysis and morphological evidence, we propose two new combinations, elevating the two varieties to species level, namely D. yinzhengii and D. gamosepalus.

中国广东省丹霞地貌特有的一个新种--平远毛竹（Gesneriaceae），以及毛竹中的两个新组合

本文描述了中国广东平远县丹霞地貌特有的平远裸子植物（Didymocarpus pingyuanensis），并绘制了插图。本种可通过其花萼深 5 裂至深 5 裂的程度来与异叶石楠（Didymocarpus sect.其花萼深 5 裂，约占其长度的四分之三。利用核核糖体内部转录间隔序列（ITS）研究了该新种在Didymocarpus中的系统发育位置。根据系统发生学分析和形态学证据，我们提出了两个新的组合，将这两个变种提升为种，即 D. yinzhengii 和 D. gamosepalus。

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.
