The crested shape of this cactus presents the typical compact fan arrangement that makes each exemplar absolutely unique, never identical to another and for this reason so much appreciated by collectors. In its normal form it is a solitary-bearing globose cactus, which occasionally glows at the base. Its stem, light green tending to olive green, concave at the apex, takes the name 'multicostatus' for the large number of slender ribs, well furrowed and with a very wavy shape, equipped with white woolly areolas. The radial spines are thin and almost translucent white, while the central spines are larger, long, rigid and tending upwards, white-reddish. The flowering takes place in spring-summer at the apex of the plant, generating small funnel-shaped flowers of a pale pink color with purple central streaks.
