The Lecythidaceae is a family of tropical trees found in Africa, Madagascar, Southeast Asia, and the New World tropics. It reaches its greatest diversity in the Neotropics and is best known for the Brazil nut of commerce (Bertholletia excelsa) and the cannon-ball tree (Couroupita guianensis). The latter species, although native to the Neotropics, is planted as an ornamental and botanical curiosity in subtropical and tropical botanical gardens throughout the world. The database includes all names in the family with the status (accepted or unaccepted) and synonymy provided for each name. The names have been abstracted from the most recent monographs of the family. A more comprehensive database, especially of the New World species, is found as part of the Virtual Herbarium of The New York Botanical Garden.
