Cochemiea wrightii is a species of Cochemiea found in Mexico and the southern United States.[2]
Cochemiea wrightii grows as a solitary cactus with dark green, flattened, spherical to briefly cylindrical shoots measuring 3 to 8 cm (1.2 to 3.1 in) in diameter. The cylindrical warts do not produce milky juice, and the axillae are bare. It has up to 3 dark, hooked central spines, each 1 to 1.2 cm (0.39 to 0.47 in) long. There are also up to 12 whitish marginal spines, 8 to 12 millimeters long, with the upper ones being shorter and dark-tipped.
The flowers are magenta to bright purple, rarely white, and up to 2.5 cm (0.98 in) long and wide, with perianth segments that are reflexed. The egg-shaped to spherical fruits are purple, up to 2.5 cm (0.98 in) long, and contain black seeds.[3]
