T.

Rhoeo is recovered as an independent lineage at the base of the

T.
sect.
Cymbispatha ( sensu

T.
commelinoides group, being well-supported (
BS= 76;
BI= 5) and characterized by: herbaceous stems (Character 4, homoplastic); distichously-alternate leaves (Character 6, homoplastic), with membranous leaf-blades (Character 10, homoplastic), and acute apex (Character 20, homoplastic); equal (Character 40, homoplastic), basally fused (Character 42), not overlapping cincinni bracts (Character 44, homoplastic); keeled dorsal sepal (Character 56, homoplastic), chartaceous sepals (Character 57, homoplastic), rotund to rhomboid petals (Character 61, homoplastic), and pistil shorter than the stamens (Character 86, homoplastic) (Figs 3, 4A).
Tradescantia
sect.
Cymbispatha is recovered as sister to a small, well-supported (
BS= 79;
BI= 4) clade, herein called the
T.
zebrina group, composed by
T.
sect.
Campelia,
T.
