Echinofossulocactus lamellosus

It is a globular cactus with a solitary habit. Its light green, tending to olive green, stem, concave at the apex, has multiple slender, well furrowed ribs of a very wavy shape, equipped with white downy areoles. The radial spines are thin and of a white color, while the central ones are much larger, longer, flat and slightly curved upwards, of a yellowish color. Flowering occurs at the apex of the plant, generating small, funnel-shaped white flowers with purple central streaks.
