Congruence between morphological and molecular datasets. A, majority-rule tree showing the sections and series proposed by Hunt (1975, 1980, 1986b) color-coded; the five newly proposed subgenera are represented by the black bars; Tradescantia guatemalensis C.B.Clarke ex Donn.Sm. is depicted in red, to highlight its placement as sister to Elasis hirsuta (Kunth) D.R.Hunt; the ● represents Tradescantias.s.; Bremer Index support values are depicted over the branches, while bootstrap support values are depicted under the branches B simplification of the current hypothesis for phylogenetic relationships in tribe Tradescantieae, based on molecular data. Thyrsanthemum Pichon and Weldenia Schult.f. are depicted in red since they were not sampled in the present study. Modified from Hertweck and Pires (2014).
