About Cochemiea blossfeldiana (Boed.) P.B.Breslin & Majure
Cochemiea blossfeldiana typically grows alone, though it sometimes forms clusters. It has spherical to shortly cylindrical gray-green bodies, reaching 5 cm (2.0 in) in height and 3 to 4 cm (1.2 to 1.6 in) in diameter. Its conical warts lack milky sap, and its axillae are thinly woolly. The plant has 4 dark brown to black central spines that are 1 to 1.2 cm (0.39 to 0.47 in) long, with the lowest spine hooking outward and the upper spines growing straight. It also bears 15 to 20 marginal spines, which are yellow with dark tips and measure 0.5 to 0.7 cm (0.20 to 0.28 in) long. Its funnel-shaped flowers are white with pink to crimson stripes, 2 cm (0.79 in) long and 2 to 4 cm (0.79 to 1.57 in) in diameter. Its club-shaped fruits are orange-red and contain black pitted seeds. This species grows in decomposing granite and gravelly soil in Baja California, Guadalupe Island, and Cedros Island, Mexico, at elevations between 0 and 150 meters. It occurs on arid coastal plains in the Lower Sonora Desert zone at Santa Rosalillita, on steep coastal slopes at Punta Baja, Boca Marrón, and Punta María, and further south near Mezquital.
