Unusual gray-green offsetting cactus from southern Mexico with bright yellow flowers. Stems reach about 1.2-1.6 inches in diameter and plants several times that. Older clumps can be quite striking. Low tubercles, no ribs, 1 central spine, and 7-8 dark radial spines. Areoles are dimorphic (spines at the tip, flowers at the axils). Found in one or two locations in Oaxaca. This monotypic genus has been associated with Coryphantha, Escobaria and Neobesseya.
