Cucurbita digitata A.Gray

Cucurbita digitata, also known as finger-leaf gourd, is a species in the Cucurbitaceae family. It is native to arid regions in the Southwestern United States and Northwestern Mexico, including Arizona, New Mexico, and northern Baja California. This species is part of a group of xerophytic Cucurbita plants that are adapted to hot, dry environments with well-drained, gravelly soils. C. digitata is closely related to other Cucurbita species such as C. californica, C. cordata, C. cylindrata, and C. palmata, with which it can hybridize. The species is relatively uncommon and grows in areas with low rainfall. Its fruits are green and mottled, turning yellow when mature, and are round with stripes.
