Proboscidea is a genus of flowering plant in the family Martyniaceae, some of whose species are known as devil's claw, devil's horn, ram's horn, or unicorn plant. The plants produce long, hooked seed pods. The hooks catch on the feet of animals, and as the animals walk, the pods are ground or crushed open, dispersing the seeds.
The fruits of some species are edible before they ripen and become woody; some species (particularly parviflora) are also used in basket weaving.
Proboscidea lutea is a synonym of Ibicella lutea.
