Phylogeny of economically important Phaseoleae legumes. The phylogeny is condensed from that presented in Stefanovic et al. (2009). The nodal dates are the minimum date of the range based on 32.1 million years ago (MYA) date of "A" node representing the divergence of the Phaseoleae legumes from Apios americana. The haploid chromosome number and C-value [in piocgrams (pg)] are from the Plant C-Value Database http://data.kew.org/cvalues/; verified May 5, 2009).
