摘要

产于中国秦岭太白山的蔷薇科植物Sorbustapashana被视为S.tianschanica的异名。这两个物种都属于一个独特的类群，其特点是芽被白色绒毛，花朵相对较大，果实为红色。然而，在基于质粒的系统发育分析中，这两个物种并没有聚类在一起。从形态上看，S.tapashana 与 S.tianschanica 的区别在于花序梗、花梗、轴、背面中脉两侧有持久的白色绒毛，小叶每侧有 31-51 个齿，伞房花序和果实小得多。因此，S.tapashana 在这里被恢复为一个独立种。

Resurrection of Sorbustapashana (Rosaceae) based on molecular and morphological evidence.

Sorbustapashana (Rosaceae) from Taibai Shan, Qinling, China, has been treated as a synonym of S.tianschanica. Both species belong to a distinctive group characterized by white tomentose buds, relatively large flowers, and red fruits. However, these two species do not cluster together in the plastome-based phylogenetic analysis. Morphologically, S.tapashana differs from S.tianschanica by its persistent white tomentose on the peduncle, pedicels, rachis, both sides of the midrib on abaxial surface, its leaflets with 31-51 teeth on each side and much smaller corymbs and fruits. Therefore, S.tapashana is reinstated as a distinct species here.

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.
