Cucurbita maxima, one of at least four species of cultivated squash, is one of the most diverse domesticated species. This species originated in South America from the wild Cucurbita andreana over 4000 years ago. The two species hybridize quite readily but have noticeably different calcium levels. Only long-vining plants are known in this species.
