Gymnocalycium kroenleinii

A small solitary flattened globular cactus, to about 6 cm across, from rocky ground at 1,250–1,450 m in the Sierra de Malanzán of La Rioja, Argentina. It does not offset, so it is propagated only from seed. Grow it as a highland Gymnocalycium: bright light, summer water and a cold, dry winter.
