Molecular phylogeny and divergence times of the genus Hedysarum (Fabaceae) with special reference to section Multicaulia in Southwest Asia

A total of 93 species of Hedysarum from diverse biogeographic regions, in particular from southwest Asia, were included in phylogenetic analyses using nuclear (ITS) and plastid DNA sequences (trnL–trnF and matK). Maximum likelihood and Bayesian analyses of combined plastid data retrieved Hedysarum as monophyletic, whereas phylogenetic analyses of the nuclear data inferred Hedysarum as non-monophyletic. In both datasets, Hedysarum comprised three...
