From Flora of Indiana (1940) by Charles C. Deam

Infrequent to frequent, but plentiful where found, in the southern part of the state. Usually abundant in hard, white clay soil in low, flat, fallow fields and in habitats similar to those of the preceding species. Probably also infrequent in the sandy areas of the northwestern part of the state, although there are specimens only from Starke County. Our specimens vary somewhat in the length of their awns, but I do not think the variation has any taxonomic value.
