Desmanthus bicornutus

A small, upright-standing shrub that grows to about 3 meters in height, Desmanthus bicornutus has a woody base. Young stems are often a deep red color; older stems are shiny red or brown. The compound bipinnate leaves are between 9 cm and 18 cm long. Desmanthus bicornutus blooms in condensed spikes of 25-60 flowers. These flowers may be perfect (occurring apically), functionally male (occurring towards the base of the flower head above the sterile flowers but below the perfect flowers), or sterile. It bears up to a dozen edible linear pods on fruiting stalks up to 5 cm long. Pods are up to 10 cm long and 5.5 mm wide. Immature pods are red but these turn to a dark brown as they mature. ==Distribution==

Desmanthus bicornutus grows in the states of Baja California Sur, Chihuahua, Sinaloa, and Sonora in Northern Mexico as well as the central states of Colima, Guerrero, Jalisco, Michoacán, Nayarit, and Veracruz. In the United States, D. bicornutus grows naturally only in the state of Arizona. ==Ecology==

This plant favors clay, rocky, or sandy soils in its native range. At higher elevations, D. bicornutus can be found amid oak forest and in grasslands. At lower elevations, this plant is found near canyons, roads, and waterways. It will also regrow in environments ravaged by wildfire. ==Use==

In Guerrero, Mexico, D. bicornutus beans are used in the making of salsa. ==References==
