WOODSIA OBTUSA. 



The fronds, which are lanceolate, are sub-tripinnale, clothed 

 beneath with glandulous hairs; the pinnae are triangularly 

 elongate; the pinnules oblong, rounded at the apex, and 

 crenate on the margin. 



Sori terminal. 



Indusium profoundly laciniated. 



Fronds terminal, and adherent to a somewhat tufted rhizoma. 



Length of frond twelve inches; colour yellowish green. 



Mr. Henderson, of Wentworth, has been kind enough to 

 send me a plant, and Mr. G. Norman, of Hull, fronds. 



The illustration is from a plant in my own collection.
