Extremely local in this state. It has been reported from only Clark and Jefferson Counties. I found it in talus at the base of a cliff along Little Blue River near the site of Carnes Mill about 2 miles south of Grantsburg in Crawford County; in talus on rocky ledges of the slope of Buck Creek where the creek parallels the road north of Dogwood in Harrison County; and in talus of the rocky slope of the North Fork of the Muscatatuck River about half a mile above Vernon, Jennings County.
