Cucurbita is a genus in the gourd family Cucurbitaceae first cultivated in the Americas and now used in many parts of the world. It includes species grown for their fruit and edible seeds (the squashes, pumpkins and marrows, and the chilacayote), as well as some species grown only as gourds. They have bicollateral vascular bundles. Many North and Central American species are visited by specialist pollinators in the apid group Eucerini, especially the genera Peponapis and Xenoglossa, and these bees can be very important for fruit set.
Several species of Cucurbita are native to North America, including C. foetidissima (finger-leaved gourd), C. digitata (calabazilla), and C. palmata (coyote melon). These plants produce gourds and form large, fleshy, tuber-like roots.
