This southern fern is most frequent in southern and 

 southeastern Iowa. Several specimens from Allamakee 

 county and one from Steamboat Rock, though not typical, 

 we have referred to this species. The Steamboat Rock 

 specimens may not be unusual, as Melica diffusa, another 

 southern plant, has found its way as far north as this 

 point. In Muscatine county the species occur in somewhat 

 damp clay, sandy woods, while at Steamboat Rock it is 

 found in black, rich, sandy woods.
