Proboscidea althaeifolia (Benth.) Decne.
Desert Unicorn-plant, Devil's Claw
Pedaliaceae (Sesame Family)
Synonym(s): Martynia althaeifolia, Martynia arenaria, Proboscidea arenaria
USDA Symbol: pral4
A coarse plant with stems lying on ground and few yellow to orange, bilaterally symmetrical flowers in racemes.
As the plump fruit matures, it divides into halves and its outer, fleshy layer peels off, revealing the hard inner portion of the fruit, the single horn of which splits into two "devil's claws." There are several species in the Southwest, some with pink or magenta flowers. The dark fibers in the pods are used with fibers of other plants in weaving fine baskets.
