in the vicinity of Georgian Bay. 
Pellaea atropurpurea itself is reported from the Andes, 
though I have seen no South American material of this 
species. It occurs more or less throughout Mexico as 
is indicated by specimens from Chiapas in the extreme.

Sonora in the northwest. In the United States it occurs 
in Arizona (Conservatory Canyon, Huachuca Mts.) 
and extends thence eastward io ithe Atlantic, as is tesd- 
fied by abundant material from nearly all the southern 
states in which there are rock outcrops suitable for its 
growth. With a single exception, the most northerly 
stations represented by specimens in the Gray Her- 
arium are eastern Kansas, ceniral Missouri, southern 
Illinois and Indiana, central and eastern Pennsylvania, 
western New York, northern New Jersey, and wester? 
New England. 
In New York there are several specimens from the 
vicinity of Syracuse, one from Seneca Lake and one 
from Fowler in Si. Lawrence Co. In New England tt 
is abundant in western Connecticut and southweste™ 
Massachusetts, and occurs at North Pownal, Dorset, 
and Burlington, Vermont. There are specimens from 
only two stations east of the Connecticut River, Mt. 
Toby, Sunderland, Massachusetts, and Lime Rock, 
Lincoln, Rhode Island, though I have definite informa- 
tion of a third locality in Bolton, Connecticut. 
References to Pellaea in ihe southern counties of 
Ohio are probably based at least in part on this species 
though I have seen no specimens of it from that stat 
and Prof.’ Pickett’s station in southeastern Nebraske

limits just outlined. The single exception noted abr. :
