Where it grows wild

Known only from central Bolivia. Like other former Sulcorebutia, it probably grows on open rocky or grassy slopes in dry mountain scrub, often half-buried among stones and grass tufts. This is a genus-level inference; the published accounts are thin.

Recorded at 2,500 to 3,000 m, median 3,000 m, from only three records with elevations.
