O. pinkavae is a small plant with compact clumps of pads (4- to 6(10)- inches tall), normally growing from a central root system composed of a branching, thickened tap root. The pads are bluish green and generally tuberculate with small areoles set relatively far apart and bearing 0- to 2(4) slender spines. The flowers are pink with green stigmas (sometimes flowers are magenta or nearly white, but apparently never orange or yellow). The fruits are dry, and the seeds relatively large and irregular in outline.

O. pinkavae is found in the Arizona Strip of northwestern AZ and southwestern UT; it is also found north up some of the valleys of southwest UT, perhaps 50 or more miles. It may be in NV too, but isn’t documented from there yet. It is a grassland and high desert plant, found mostly between about 4000 and 6000 ft, but on the Kaibab Plateau and near Colorado City, AZ and Kanab, UT, it sometimes occurs in open pinyon-juniper woodland where it grows to at least 7000 ft.
