Coryphantha poselgeriana

This globe-shaped cactus tends to become cylindrical with growth reaching 30 cm in height and 18 cm in width. It has an opaque bluish green stem; woolly at the apex and equipped with tuberculate ribs above which are the white areoles. The radial and central spines emerge from this shaft; the first ones are numerous, curved white in color, which then turn brown with dark tips. Instead, the central plants are more robust, straight and dark with red tips. The flowers of C. poselgeriana bloom at the apex of the stem, with colors ranging from whitish pink to red and in some areas of Mexico even yellow.
