Cucurbita palmata
Cucurbita palmata is a species of flowering plant in the squash family known by the common names coyote melon and coyote gourd. It is similar to "Cucurbita californica", "Cucurbita cordata", "Cucurbita cylindrata", and "Cucurbita digitata" and all these species hybridize readily. It was first identified by Sereno Watson in 1876. These species form the only restricted xerophyte species group in the genus "Cucurbita". Each member of this species group is native to the Southwestern United States and Northwestern Mexico where they are relatively uncommon. Each group member is found in hot, arid regions with low rainfall. They prefer  soil that is loose, gravelly, and well-drained. "C. palmata" is native to northeastern Baja California, southeastern California, and southwestern Arizona to a point near the Colorado River. The juvenile leaves of "C. cylindrata", "C. cordata", "C. digitata", and "C. palmata" show a high degree of similarity, but their mature leaves are visibly different, as are their root structures. "C. palmata" and "C. digitata" are sympatric, with "C. palmata" separating the ranges of "C. digitata" at the juncture of Baja California, California, and Arizona. "C. palmata" fruits are diffuse green mottle that turns yellow at maturity, striped, and round. Description . "Cucurbita palmata" is a sprawling vine with rough, stiff-haired stems and leaves. The dark green, light-veined leaves are sharply palmate with usually five long triangular points. The stiff, curling yellow flowers are 6 to 8 centimeters wide. The plant bears smooth spherical or oblate squash fruits 8 to 10 centimeters wide. The fruits may be bright yellow to dark green and may have white stripes. The fruit is distasteful and not edible.
