Morphological key traits of species with putative hybrid origin produced by the cross between subsect <i>Saxatile</i> + subsect <i>Arvenses</i> (<i>ssSax+ssArv</i>) and subsect <i>Supinae</i> (<i>ssSup</i>) parental lineages based on the results obtained in the *BEAST multilabelled species tree analysis (Figure 5).
