A terrestrial hybrid quillwort, Isoetes ×angeloi, hyb. nov., (Isoetaceae) from Sicily
ABSTRACT A sterile hybrid between diploids Isoetes gymnocarpa and I. longissima (s.s.) (Isoetaceae) is described from Anguillara, Trapani Province, Sicily, Italy. Although closest in morphology to I. gymnocarpa with which it was growing, the small group of hybrid plants also exhibited features of I. longissima which occurred abundantly within 50 m of the site. In addition to such classic hybrid characteristics as larger plant size (hybrid vigour) and polymorphic, aborted megaspores with ornamentation intermediate between that of the putative parents, the microspores of the hybrid exhibit both the arachnoid ornamentation features of I. gymnocarpa and the echinate features of I. longissima (s.s.). Isoetes ×angeloi, hyb. nov., is the first non-aquatic Isoetes hybrid to be formally described. It is also the first hybrid quillwort to be confirmed from the Mediterranean Basin.
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.
