Handroanthus
Genus
Handroanthus is a genus of flowering plants in the family Bignoniaceae. It consists of 30 species of trees, known in Latin America by the common names poui, pau d'arco, or ipê. The latter sometimes appears as epay or simply ipe (unaccented) in English. The large timber species are sometimes called lapacho or guayacan, but these names are more properly applied to the species Handroanthus lapacho and Handroanthus guayacan, respectively.
