Description
Summary:Charophytes are aquatic green macroalgae, which inhabit fresh and brackish water ecosystems. In this study, four species belonging to the genus were examined to determine their taxonomic status. Morphological characteristics of the plant bodies as well as plastid B barcoding genes were applied to test the relations among species. Plants were initially classified using morphological features into four species: , , and , and twelve quantitative characters were used in a principal component analysis and discriminant analysis to determine groupings among the species and to determine the morphological features that best separated the groups. In the component analysis and discriminant analysis, results showed that only and partly formed separate groups. The other species and were only partially distinguishable. All species from one molecular group, and no differentiation in the B variability between them has been found.
