This variety is known only from southern Indiana where it has been found in rather moist, sandy soil along Whitewater River, in Dearborn and Franklin Counties, along the Patoka River, in the talus of the sandstone cliff along the Ohio River at Rockport, on the wooded bank of the Ohio River at Derby in Perry County, and in a low place in a woods 9 miles north of Rockport. The plant is easily recognized in the field by its large drooping leaves and by the whole plant usually being at least twice as large as the typical form of the species.
