''Tabebuia'' is a genus of flowering plants in the family Bignoniaceae.〔Eberhard Fischer, Inge Theisen, and Lúcia G. Lohmann. 2004. "Bignoniaceae". pages 9-38. In: Klaus Kubitzki (editor) and Joachim W. Kadereit (volume editor). ''The Families and Genera of Vascular Plants'' volume VII. Springer-Verlag: Berlin; Heidelberg, Germany. ISBN 978-3-540-40593-1〕 The common name "roble" is sometimes found in English. ''Tabebuias'' have been called "trumpet trees", but this name is usually applied to other trees and has become a source of confusion and misidentification. ''Tabebuia'' consists almost entirely of trees, but a few are often large shrubs. A few species produce timber, but the genus is mostly known for those that are cultivated as flowering trees.〔David J. Mabberley. 2008. ''Mabberley's Plant-Book'' third edition (2008). Cambridge University Press: UK. ISBN 978-0-521-82071-4〕 ''Tabebuia'' is native to the American tropics and subtropics from Mexico and the Caribbean to Argentina. Most of the species are from Cuba and Hispaniola.〔Susan O. Grose and Richard G. Olmstead. 2007. "Evolution of a Charismatic Neotropical Clade: Molecular Phylogeny of ''Tabebuia'' s.l., Crescentieae, and Allied Genera (Bignoniaceae)". ''Systematic Botany'' 32(3):650-659. 〕 It is commonly cultivated and often naturalized or adventive beyond its natural range. It easily escapes cultivation because of its numerous, wind-borne seeds.〔George W. Staples and Derral R. Herbst. 2005. "A Tropical Garden Flora" Bishop Museum Press: Honolulu, HI, USA. ISBN 978-1-58178-039-0〕 In 1992, a revision of ''Tabebuia'' described 99 species and one hybrid.〔Alwyn H. Gentry. 1992. "Bignoniaceae: Part II (Tribe Tecomeae)". ''Flora Neotropica'' Monograph 25(part 2):1-373.〕 Phylogenetic studies of DNA sequences later showed that ''Tabebuia'', as then circumscribed, was polyphyletic.〔 In 2007, it was divided into three separate genera.〔Susan O. Grose and Richard G. Olmstead. 2007. "Taxonomic Revisions in the Polyphyletic Genus ''Tabebuia'' s.l. (Bignoniaceae)". ''Systematic Botany'' 32(3):660-670. (See ''External links'' below).〕 Primavera (''Roseodendron donnell-smithii'') and a related species with no unique common name (''Roseodendron chryseum'') were transferred to ''Roseodendron''. Those species known as ''ipê'' and ''pau d'arco'' (in Portuguese) or poui were transferred to ''Handroanthus''. Sixty-seven species remained in ''Tabebuia''. The former genus and polyphyletic group of 99 species described by Gentry in 1992 is now usually referred to as "''Tabebuia'' sensu lato".〔 == Species == All of the species in the first two columns below were recognized and described by Gentry in 1992.〔Alwyn H. Gentry. 1992. "Bignoniaceae: Part II (Tribe Tecomeae)". ''Flora Neotropica'' Monograph 25(part 2):1-150.〕 Listed in the third column are species names that have been used recently, but were not accepted by Gentry. The currently accepted synonym for each is in parentheses. Some recently used names in ''Tabebuia'' that were not recognized by Gentry are not listed in the third column below because they apply to species that are now in ''Handroanthus''. ''Tabebuia spectabilis'' is an obsolete name for ''Handroanthus chrysanthus'' ssp. ''meridionalis''. ''Tabebuia ecuadorensis'' is now synonymized under ''Handroanthus billbergii''. ''Tabebuia heteropoda'' is now synonymized under ''Handroanthus ochraceus''. No species that is now assigned to ''Roseodendron'' or to ''Handroanthus'' is listed below. Authorities are cited for some of the names below. These can be found in Gentry (1992)〔 or at the International Plant Names Index.〔''Tabebuia'' in International Plant Names Index.
