It has 7–10 very flat ribs with faint transverse grooves. Up to six thin, almost hair-like white spines, darker at the tips, grow up to 3 mm long. The white flowers have a faint reddish throat, measuring 3–4 cm in both length and diameter. The greenish-brown, egg- to spindle-shaped fruits grow up to 2.5 cm long. [3]

Native to Catamarca Province and Córdoba Province, Argentina, Argentina, it is found from altitudes 100 meters up to 500 meters. It is found growing semi buried at the edge of saline grasslands growing along with Gymnocalycium schickendantzii , Gymnocalycium bodenbenderianum , and Setiechinopsis mirabilis . [4]
