Wislizenia refracta, common names jackass-clover or spectacle fruit, is one of three recognized species in its genus Wislizenia, although some authors have suggested considering them as subspecies.^[2] Wislizenia refracta is native to northwestern Mexico and the southwestern United States. It has been reported from Chihuahua, Sonora, trans-Pecos Texas, New Mexico, Arizona, Utah, Nevada and from California (Riverside, Kern and San Bernardino Counties).^[3] The species occurs in sandy flats, in desert scrub, and on disturbed sites such as roadsides.^[4]

Wislizenia refracta is an annual herb up to 200 cm (78.5 in) tall. Leaves are trifoliate, the leaflets ovate (egg-shaped), up to 5 cm (2 in) long. Flowers are yellow.^[5]^[6]^[7]^[8]^[9]
