A Hurvey of the Phytogeograpliy of the Aictic American Arcliipelago 
Pteridophyta. 
Polypodiaceae, R. Br. 
1. Woodsia ilvensis, (L.) R. Br. 
W. hyperborea, Tayi.or, Pl. Baff., Macoun, Cat. 
Distribution. [Nottingham Island, Bell (ex Macoun, 1. c.]; Baffin Land: 
Kingnait (NHM, KH) and Niatoling in Cumberland Gulf, Cape Searle, Scotts Bay, 
Tayloe (1. c); Ellesmereland: »Edwards Grief«, Hart, Cape Viele, Simmons. 
Geographic area. Greenland, northern North America, eastern and middle 
Asia, northern and middle Europé. 
In my opinion all specimens from the Arctic Islands are referable to the var. 
alpina, (Bolt.) Aschers. & Graebn. TAtLOR, 1. c, p. 333, has a note which points 
in the same direction: »None of the roots brougt home have developed into W. 
hyperborea. They have all turned out to be either W. ilvensis or W. glabella, though 
the f ronds brought home correspond with W. hyperborea». This confirms the opinion 
stated in my Flora EUesni. about the near relations between the two forms, as for 
W. glabella. there niay be some mistake, or else it is to be placed under W. ilven- 
sis, as Gelbrt has done in Ostenfbld, Flora Aret. 
2. Woodsia glabella, R. Br. 
W. hyperborea, Hookkk, Exp. Fox. 
Distribution. North Somerset: Port Kennedy, Walker (KH); Baffin Land: 
Kingnait (KH, NHM) in Cumberland Gulf, Cape Searle, Scotts Bay, Taylor (Pl. 
Baff.); Ellesmereland: Edwards Grief, Haet, and about ten other locahties within 
the Archaean territory, Simmons. 
Geographic area. Greenland, northern North America, eastern and nor- 
thern Asia, mountains of Europé. 
In the NHM I have seen one specimen. labelled »either Mr. Parry's 3:d 
voyage or Sir John Ross' last — Mr. James Ross»; it comes most probably from 
Boothia or North Somerset, where the collection from John Ross' second voyage is 
brought together. If it should be from Parry'8 third voyage it most probably still 
is taken in North Somerset and not in the barren limestone- region of Port Bowen. 
Taylor, 1. c, p. 333, speaks of W. ilvmsis as occurring on »granitic rocks», and 
the same seems to hold good for W. glabella also. 
3. Oystopteris fragilis, (L.) Bernh. 
Aspidium fragile, Hooker, App. Parry III. 
Distribution. Victoria Land: Minto Inlet, Anderson (ex Hookeb, Coll.); 
Baffin Land: Kingnait (KH) and Kekertcu i.i ( umherland Gulf, Scotts Bay, Taylor
