In 1992, a revision of "Tabebuia" described 99 species and one hybrid. Phylogenetic studies of DNA sequences later showed that "Tabebuia", as then circumscribed, was polyphyletic. In 2007, it was divided into three separate genera. 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".
