- Abstract
The taxonomy of Astragalus sect. Dissitiflori from Europe is shaped by a controversial nomenclatural history and considerable morphological variation that requires numerical methods to facilitate species delimitation. Besides molecular methods, multivariate analysis of morphological traits has long been recognised to offer important and often complementary evidence in taxonomic research. We applied Multiple Discriminant Analysis based on 14 field-measured morphological characters to test the phenetic distinctiveness of A. pseudoglaucus, A. tarchankuticus, A. vesicarius s.l., A. peterfii and A. pallescens. In addition, we attempted to find the most discriminative morphological traits that separate the taxa investigated. Distinctness of A. tarchankuticus from A. pseudoglaucus and A. vesicarius is clear, whereas the latter two taxa are fairly close to each other. A. peterfii and A. pallescens separated from the other three species, but were found to be close morphologically. Five morphological characters proved to be useful traits to distinguish the species surveyed. Our findings contribute to a refined taxonomy of Astragalus and may serve as a starting point in a molecular systematic study of sect. Dissitiflori.
