Cucurbita okeechobeensis, the Okeechobee gourd, is a species of gourd in 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.[3][4] Once abundant,[3] it has state and federal listing as an endangered species.[5] One of its peculiarities is the yellow corolla not so common in other Cucurbita species.
Description
A climbing vine, C. okeechobeensis leaves have irregular serrate margins with 5 to 7 angular, shallow lobes. Overall the leaf blades are heart or kidney-shaped. Young leaves are covered with downy hair. The bell-shaped flowers are cream-colored, with long corollas (6 to 7 cm).
