Analysis of morphological characters of Chara baltica, C. hispida, C. horrida, and C. rudis from Europe
Morphological characters of Chara baltica, C. hispida, C. horrida, and C. rudis from different localities in Central Europe and Scandinavia were analyzed. The plants were preliminarily classified using specific qualitative features into four species: C. baltica, C. hispida, C. horrida, and C. rudis. Of the 14 characters, all were used in principal-component and cluster analyses, and 12 were applied in a discriminant analysis. In the discriminant analysis, the most useful characters for distinguishing particular species were selected. The methods (canonical discriminant and canonical analyses) used herein offered good differentiation between brackish water species C. horrida and C. baltica and fresh water species C. hispida and C. rudis. The analysis showed that the two morphologically very similar species C. hispida and C. rudis are only partially distinguished.
