Tumamoca macdougalii
Tumamoca macdougalii Rose is a member of the Cucurbitaceae or gourd family. Also called the Tumamoc globeberry, it is native to a very narrow area of the Sonoran Desert, and is found in both Sonora and Arizona. It is one of two species in genus Tumamoca. Tumamoca macdougalii is a monoecious vine climbing over various shrubs. Stems die in the fall, but tuberous roots generally persist through the winter. Leaves are deeply 3-lobed, nearly cleft, each lobe similarly divided into several sections. Flowers are pale yellow with narrow corolla lobes. Pistillate (female) flowers are solitary in the leaf axils; staminate (male) flowers in racemes of 2-6 flowers. Fruits are spherical, red, rarely yellow, about 10 mm (0.4 inches) in diameter. Uses
The Seri and Tohono O'odham eat the fruits of T. macdougalii. References
