Comments: The Doubleclaw and several other species of Proboscidea are unusual and beautiful with their large showy flowers. Their unique "Devils Claw" split seed pods with hooks on the ends attracts a lot of attention from many fans of these interesting plants. The "hooks" on the seedpods are "caught" on the fur and feet of passing animals thus spreading the seeds to new locations.

In Southwest Desert Flora also see Desert Unicorn-plant, Proboscidea althaeifolia.

Doubleclaw is used by the Havasupai as a dried food, and the seeds also used for food and the pods are used for the black designs in baskets. See ethno-botanical uses at Native American Ethnobotany, University of Michigan, Dearborn.
