Low, spiny, clumping cactus from western Mexico with outstanding large (for the genus) red flowers. Stems grow to about 4 inches in diameter. Each areole has 4-6 central spines (2 of which are hooked), and dozens of radial spines. Flowers are 2-3 inches wide. From high elevations in Chihuahua, Jalisco, Sinaloa. Apparently related closely to Cochemiea. Formerly in the genus (now subgenus) Mammillopsis. There is apparently also a white-flowered form in cultivation.
