Stenocactus coptonogonus

A small globular cactus, 7 to 10 cm across, with 10 to 15 broad, stout ribs and white flowers striped purple. Unlike most Stenocactus it has few, thick ribs. It comes from the high central Mexican plateau at about 1,800 to 2,400 m, so it wants full sun, a wet warm summer and a cold dry winter.
