86 AMERICAN FERN JOURNAL 
Noie on the range of Pellaea Breweri D.C. Eaton: 
As there has been much confusion in the distinction — 
of this species and P. glabella var. occidentalis, and as 
numerous specimens of P. Breweri have been distributed 
under the name P. occidentalis, it seems well to note 
briefly the characters of P. Breweri and what is known 
about its range. 
This fern was originally described by D. C. Eaton 
from specimens from the Sierra Nevada Mountains of 
California." It is clearly characterized by its exvra- 
ordinarily brittle stipes and non-coriaceous fronds, and 
by the peculiar form of its pinnae, which are usually 
mitien-shaped, or two-lobed, with the anterior lobe 
‘considerably larger than the posterior. It is well il 
lusirated in Eaton’s Ferns of North America 1: pl. 43. 
The range of P. Breweri is from the Sierra Nevada 
Mountains, through the basin ranges of Nevada and 
Utah, to the Blue Mountains of Oregon, central Idaho, 
and western Wyoming. Throughout its range it i 
remarkably uniform in character. Unlike the varieties 
of P. glabella it seems to grow by preference on graniti¢ 
rocks. 
There are a large number of specimens of this fern in 
the Gray Herbarium. It seems unnecessary to cite 
those from California and Nevada, as there has been 
no confusion concerning it in those states. The follow- 
ing are the specimens from the northern and easter 
portions of its range:
