Notes ON AMERICAN FERNS—XIII 3 
as well; and as there is no likelihood whatever that so 
large a series of individuals from some distant western 
region could have been introduced accidentally into 
the West Virginia collection, the latter locality data 
may properly be regarded as true. The station in 
question, which is on the boundary line of Virginia, 
extends the range of this species from Ontario and 
Quebec, a distribution not exactly paralleled by any 
other fern, so far as the writer knows. The distribu- 
tion and distinctive characters of W. scopulina and 
related species form the subject of notes to be published 
shortly. 
CHEILANTHES Eatonit Baxer.—This species, though 
shown by Eaton! to be amply distinct from C. tomentosa 
Link, has rather commonly not been so recognized but 
regarded instead as a variety of C. tomentosa, and inas- 
much as occasional specimens of each are still mis- 
identified as pertaining to the other, it seems desirable 
to point out again some of the characteristic differences. 
Cheilanthes tomentosa, described originally from culti- 
vated material, ranges from Virginia to Georgia, west- 
ward through Terine:see, Alabama, Arkansas, and - 
Oklahoma to central Texas, the Organ Mountains of 
southern New Mexico, the Santa Catalina, Huachuca, 
and Santa Rita Mountains of southeastern Arizona, 
and sparingly into northern Mexico. It seems nowhere 
very abundant and becomes decidedly rare in the western 
portion of its range. Cheilanthes Eatoni, founded on 
Wright’s No. 816 from western Texas, ranges from 
Oklahoma and central Texas widely through New Mex- 
ico to Colorado? and central Arizona, and southward 
far into Mexico, —o at least to the State of Puebla.
