Tumamoca macdougalii

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.[4]

Uses

The Seri and Tohono O'odham eat the fruits of T. macdougalii.[5][6]
