Abstract
Proboscidea louisianica (Mill.) Thell. is a member of Martyniaceae family, known as devil’s claw or unicorn plant. Is an annual plant of almost 80 cm high with thick stem where the medullary parenchyma disorganizes and forms a wide aeriferous canal. Leaves are amphistomatic, with bifacial-heterofacial structure and normal dorsiventrality. Whole body of the plant is covered by secretory hairs. The flowers are trompet-shaped. The fruit is a dehiscent capsule of almost 10 cm length ended in a beak. When the fruit reaches maturity, the sclerenchyma fibers strongly lignify and determine its breakage in two symmetric parts (as claws, where the common name of the plant comes from) liberating the seeds. Ornamental plant, alimentary, too, because the pots can be eaten as pickles.
