Cucurbita okeechobeensis, the Okeechobee gourd, is a species of gourd belonging to the family Cucurbitaceae, native to Mexico and the United States. There are two subspecies; one is endemic to Florida, primarily in the region around Lake Okeechobee, the other to the State of Veracruz in eastern Mexico.[4][5] Once abundant,[4] it has state and federal listing as an endangered species.[6] One of its peculiarities is the yellow corolla not so common in other Cucurbita species.
