The blue-green to blue-gray shoots are spherical, depressed spherical or sometimes short columnar and reach heights of up to 5 centimeters with diameters of 6 centimeters. A long beet root is formed. The eight to twelve rounded ribs are clearly furrowed.

They are whitish and have a darker base.

The pale to bright sulfur yellow or white to light pink flowers are 4 to 5 centimeters in diameter and up to 4 centimeters long. The blue-green fruits are spherical to cylindrical and reach a diameter of up to 1.2 centimeters.[3]

The first description as Echinocactus andreae was made in 1930 by Friedrich Bödeker. The specific epithet andreae honors the honorary member of the German Cactus Society, the German cactus specialist and cactus connoisseur Wilhelm Andreae from Bensheim. Curt Backeberg placed the species in the genus Gymnocalycium in 1936.[4]
