Gymnocalycium friedrichii

Gymnocalycium friedrichii is a small solitary cactus with banded body that has perianth-segments pinkish-red with white margins (but also pale pink or almost pure white). This species is sometimes combined with Gymnocalycium mihanovichii, and sometimes kept as a separate species.
Stem: Flattened globose to elongated globose, grey green, olive green, greenish-purple, reddish brown to a dark grape colour 10-12 cm tall (or more), 6-12 cm in diameter.
Ribs: 8-14, very prominent, and sharp banded whit strong dark brown markings especially when young, and these sometimes have crossbands of lighter colors.
Radial spines: 3-6, acicular, to awl shaped, light to dark brown, somewhat twisted, 0,7-4 cm long.
Central spines: Usually absent.
Flowers: Pale-pink to purplish-pink, 6-7 cm long.
Fruit: Gray-green up to 4 cm long, diameter 1 cm.
Remaks: Gymnocalycium friedrichii and Gymnocalycium stenopleurum are sometimes combined with Gymnocalycium mihanovichii, and sometimes kept as separate species. Gymnocalycium friedrichii and Gymnocalycium stenopleurum are quite distinct from Gymnocalycium mihanovichii, but many intermediate forms are also known and nowadays it is suggested that all should be combined into only one variable species.
