Dryopteris cristata ILJ A.Gray. 



specimens are from wooded bluffs and slopes along streams. In addition 

 to my collections, it has been reported from Clark, Floyd, Monroe, and Vigo 

 Counties. It has been reported also from the dune area, and on May 30, 

 1935, R. M. Tryon, Jr. showed me large colonies of it on a north, wooded 

 slope in Memorial Park about a mile east of Michigan City. It is, without 

 question, a native here. 



A form in which the pinnae are toothed or lobed has been named and 

 has been reported from Indiana. I have a few specimens with some of 

 the pinnae toothed but I do not think it is worth while to name such 

 minor fluctuations.

 Crested Woodfern. Map 19. This species is restricted nearly to the lake 

 area where it is frequent in tamarack bogs and in low woods, usually in 

 masses of decaying organic matter. There are, however, reports of it 

 from Grant, Howard, and Monroe Counties.
