On Edwards Plateau and South Texas Plains. According to Uvalde Research and Extension Center it grows at high elevations in limestone soils and it occurs only in a small strip of about 20 miles from the Anaconcho Mountains in the southwest corner of Uvalde county, through the mountains of the Devil's and Pecos rivers, to near Dryden, Texas.

According to Dave Ferguson this species grows on east side of the upper bend of the Big Bend in Texas, but ranges south to the area of Muzquiz in Mexico. It is not in Brewster nor Presidio Counties at all, and it is not up on the Edwards Plateau or near the coast either. It blends into O. strigil toward the Stockton Plateau and Dryden in Texas.
