The name of the species derives from the Latin and literally means “neglected, forgotten”, referring to the fact that initially it was not named as an autonomous species. It is a wonderful spherical cactus that does not exceed 6-7 cm in diameter and remains slightly depressed at the apex, of a beautiful opaque dark green jagged by perfectly symmetrical and rather protruding conical tubercles. Double spines emerge from yellowish areoles: the radial ones are arranged radially almost to surround the stem, they are thin, pale yellow and very straight; the central spines are instead single and sometimes absent, dark brown, longer and more robust, facing outwards. At the apex of the cactus there is a white down characteristic of the genus Coryphantha between the spines which tend to be longer and pointing upwards: in the middle of the latter, striking funnel-shaped yellow flowers with brown central stripes will blossom, as extravagant as beautiful!
