This last variety is the most developed form, and is very different, 

 both in habit and size, from the small forms mentioned above. 



I have tried above to arrange in a key the forms represented in

Series I : var. typica; var. magna; var. Balbisii. 



Series II : var. strigosa; var. portoricensis. 



The var. hirta is probably only a slight variety of the typical 

 form. 



DRYOPTERIS CONSANGUINEA (Fee) C. Chr. 



(Revision 297, No. 33, Fig. 21.) 



The true form of this distinct species is not represented in the 

 U. S. National Herbarium, but I find some specimens, which in most 

 characters agree with it very well. I refer them to a new variety : 



DRYOPTERIS CONSANGUINEA ^QUALIS C. Chr., var. nov.
