From Flora of Indiana (1940) by Charles C. Deam
Infrequent to frequent throughout the state. Found in many habitats and in dry and moist soils. It is often found in burned-over areas in woodland and in marsh land, where it frequently forms dense stands. It is in such an area that the variation of the species can be best studied. Varieties have been described, but my studies convince me that ours is a polymorphic species. I have seen the form with reduced upper leaves growing close beside a specimen which had long leaves up to the inflorescence. In the same colony leaves may be found with bases clasping or not clasping. Individuals with the upper leaves reduced is the common form, and those with the upper leaves not reduced is less frequent.
