Basellaceae is a small tropical and subtropical family native to the Americas, southeastern Africa, Madagascar, and possibly Asia. The centre of diversity is in the Andes of northwestern South America, but the centre of origin may very well be in Africa. At present, four genera (Basella, Tournonia, Ullucus, Anredera) with a total of 19 species are recognized, most of them being succulent vines occurring in dry habitats. Some species are cultivated, and one (Ullucus tuberosus Caldas) is an important high Andean crop grown for its edible tubers.
