Phylogeny and systematics of the western Mediterranean Vella pseudocytisus-V. aspera complex (Brassicaceae)

The evolution and taxonomy of the core members of subtribe Vellinae (Brassicaceae), comprising Vella aspera, V. bourgeana, and V. pseudocytisus, is still poorly known. We reconstructed the evolutionary relationships among these taxa and other Vellinae and close Brassicaceae using nuclear ITS and plastid trnTF phylogenies, and analyzed the phenotypic traits that differentiate the infraspecific ranks of V. pseudocytisus.
