Phylogenetic tree reconstructed using the concatenated nuclear data obtained using Hyb-Seq for 76 samples of the Tamus clade of Dioscorea. Morphological, ploidy and geographic distribution trait variation is represented with circles for each sample. Leaf: filled circle, trilobed; empty circle, cordate; ploidy level: filled circle, allelic ratio >2 (estimated as polyploid); empty circle, allelic ratio <2 (estimated as diploid; see Results); geographic distribution: filled circle, W and C Mediterranean; empty circle, E Mediterranean; inflorescence: filled circle, sessile solitary; empty circle, pedunculated fascicule.
