Crescentia cujete L.
The calabash (derivative of the French word 'calebasse') tree is native to the tropical and subtropical regions of America. Its place of origin is uncertain because the species has been cultivated in the Yucatan Peninsula since pre-Hispanic times . The species grows naturally on the Caribbean islands and from Mexico through Central America to northern regions of South America. It has been introduced into India from South America. Today it is cultivated as a backyard tree in several countries across the world.
