The population at Sweetwater is an outlier, isolated from they main distribution of the species to the west by perhaps over 100 miles. At Sweetwater it grows sympatrically with O. orbiculata and O. lindheimeri, and perhaps some other close relatives, yet it remains totally distinct and easily distinguishable.

The plant in the first photo is a young but mature one, about 4 ft. in height (in the photo it looks smaller than it is). The adjacent plant in the next to last photo (possibly the same clone) is about 5 ft. tall.
