Phylogenetic tree obtained by Bayesian phylogenetic inference of the combined nuclear rDNA ITS and chloroplast ycf1 datasets of 64 Astragalus and one outgroup accession. Clade support values (BI pp/MP bs) are given at the branches of the tree. Asterisks at branches indicate pp ≥ 0.98 and bs ≥ 80%, respectively. Asterisks behind species names indicate new species names currently in the process of valid publication, while species names given in bold face mark species formerly not included within sect. Hymenostegis. Regions of origin of the species are color-coded and the areas are provided in the inserted map⁶⁵.
