192 THE WEST \IRGIXIA FLORA 



Air. Morris states that typical vulgare was common in the 

 general region ; from this it differs in its much greater size, 

 its scantier foliage, and in the shape of the pinnae. There 

 are in the National Herbarium at least two specimens, col- 

 lected in West \'irginia and North Carolina, which with 

 plants collected at Great Falls, Fairfax County, Va., by 

 William Palmer, are to be regarded as intermediate with 

 typical vulgare, mossy boulders along the Blackwater Fork 

 of Cheat RivSr (Millspaugh) .
