Echinofossulocactus coptonogonus

It is a globular cactus with a solitary habit, which can occasionally be clustered at the base. Its greyish-green stem, concave at the apex, has multiple well furrowed ribs, equipped with slightly downy white areoles. The spines are robust, curved, of a red color, which, with age, tend to whiten up. Flowering occurs in spring at the apex of the plant, generating small, funnel-shaped purple flowers with white margins.
