Ariocarpus scaphirostris

Ariocarpus scaphirostris is a species of plant in the family Cactaceae. The Ariocarpus scaphirostris was originally called Ariocarpus scapharostrus in the 1930.

Description
Ariocarpus scaphirostris grows geophytically with dark green to brown bodies, 4 to 9 centimeters in diameter, with only the warts protruding from the soil surface. The warts are somewhat triangular in cross-section, spreading, pointed, and more than twice as long as they are wide. Areoles are absent or located near the tip of the warts.

The plant is slow growing and also produces rare flowers. The magenta flowers reach a diameter of 4 centimeters, and the greenish fruits are 9 to 15 millimeters long.

Distribution
Ariocarpus scaphirostris is endemic to hot deserts gowning on shaly limestone in a single valley in Nuevo León, Mexico at elevations between 950 to 1400 meters.

Taxonomy
First described in 1930 by Friedrich Bödeker, the specific epithet "scaphirostris" is derived from the Greek "skaphe" (ship) and the Latin "rostrum" (beak), referring to the shape of the wart tips. Bödeker's original spelling, "Ariocarpus scapharostrus," was corrected by D. R. Hunt, in 1991 to comply with Article 61.1 of the International Code of Botanical Nomenclature.

Pharmacology
Hordenine, N-methyltyramine, N-methyl-3,4-dimethoxy-β-phenethylamine and N,N-dimethyl-3,4-dimethoxy-β-phenethylamine were found in Ariocarpus scaphirostris.
