The Tradescantieae are a tribe of plants in the family Commelinaceae erected by Carl Meissner in 1842.Meissner (1842) Plantarum vascularium genera secundum ordines naturales digesta eorumque differentiae et affinitates tabulis diagnosticis expositae. Weidmann, Lipsiae [Leipzig]. 406. Many genera originate from the Americas, but those in subtribes Coleotrypinae, Cyanotinae, Palisotinae and Streptoliriinae are Asian or African in origin; several species in the typical Tradescantia and other genera have become domesticated ornamental plants and naturalised elsewhere.
Subtribes and genera The following subtribes remain included, but in their review Zuntini et al.
