Analysis of the Type Material of Synedra deformis W.Sm. and Synedra vaucheriae var. Deformis Grunow (Fragilariaceae, Bacillariophyta)

ABSTRACT Despite being one of the dominant groups in the diatom flora of our rivers and lakes, the correct taxonomic identity of several Fragilaria Lyngb. taxa (formerly in the genus Synedra Ehrenb.) is often blurred by insufficient knowledge of the different morphological types. The present paper illustrates and discusses several former Synedra taxa using both light and scanning electron microscope observations. Based on the morphological analysis, Synedra deformis W.Sm. is transferred to the genus Fragilaria as Fragilaria deformis (W.Sm.) Van de Vijver & Ector, comb. nov. A second Synedra species, S. vaucheriae var. deformis Grunow, is likewise investigated but proved a later synonym of F. pectinalis (O.F.Müll.) Lyngb. The morphological results are compared with the (type) material of several similar Fragilaria species such as Fragilaria joachimii Kahlert, F. vaucheriae (Kütz.) J.B.Petersen, F. pectinalis and F. candidagilae Almeida, C.Delgado, Novais & S.Blanco. Notes on the ecology of the different species are added.

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.
