Abstract
As part of a taxonomic reassessment of species that were classified in Berkheya series Rigidae in the most recent monograph of Berkheya, the type material for Berkheya rigida and its putative heterotypic synonyms is reassessed. The original material for the basionym, Stobaea rigida, is heterospecific. Therefore, a second-step lectotype is designated consistent with predominant usage of the name Berkheya rigida. The name Apuleia rigida and its replacement name Stobaea gaertneri apply to a conspicuously radiate species and are excluded from the synonymy of Berkheya rigida. The morphological variability of Berkheya rigida is discussed.
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.
