Abstract

Cirsium wulongense (Asteraceae), a new species from Xiannü Shan in Wulong district, Chongqing, China, is described and illustrated. This new species is similar to C. sichuanense in its nodding capitula and white corolla, but differs by having leaves discolorous (vs. concolorous), abaxially grayish white and densely tomentose (vs. green, glabrous or sparsely pubescent with long multicellular hairs) and phyllaries subulate (vs. acute) at apex. It is also closely similar to C. fanjingshanense in the campanulate involucre and patent to reflexed phyllaries, but differs by its stems pubescent with densely long multicellular hairs (vs. subglabrous), leaves pinnatilobate to pinnatipartite (vs. undivided), discolorous (vs. concolorous), abaxially grayish white and densely tomentose (vs. green and glabrous), and corolla white (vs. purplish).

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.
