Gymnocalycium sutterianum

G. sutterianum is a slightly flattened globe-shaped cactus. Its stem of opaque green color is equipped with ribs and well marked tubercles and on each of them are the woolly white areoles. From the latter come out its thorns arranged in rays: they are long and thin; of white or yellowish color and curved towards the stem. The beautiful flowers of G. sutterianum bloom at the apex of the plant and present colors ranging from pink to light pink with delicate petals.
