to clear up. Thus, as late as 1893, Eaton, in the Botany 
of the Death Valley Expedition,’ indicates the range. 
as “extending to the Belt Mountains of Montana, 
and to New Mexico at Loma, on the Rio Grande.” 
Both the Montana and the ‘‘New Mexico” specimens, 
in the Eaton Herbarium, have been examined by the 
writer through the courtesy of Prof. Alexander W. 
Evans, and both belong to the puzzling western aggre- 
gate associated with P. glabella in a varietal sense by 
Professor Butters. They are very clearly not P. Brewert. 
The Montana specimen was collected in the Belt Moun- 
tains by Newberry in 1884. 
The “Loma” specimens actually come from southern 
Colorado, the rather confused history being as follows: 
In Ferns of the Southwest* Eaton cited P. Brewert 
as from New Mexico (Loew) and as having been col- 
lected “near Loma in southern Colorado, Dr. Rothrock 
< OORT aes near the headwaters of the Rio Grande.” In 
Ferns of North America? Eaton again mentioned small 
specimens collected “near Loma in Colorado, near the 
Rio Grande,” here ascribing Loew as the collector. 
The specimens in the Eaton Herbarium are marked 
in Eaton’s hand as collected in New Mexico, by Loew, 
with the locality ‘Loma, on Rio Grande” written 1n 
later. Aside from the foregoing there is no record of 
the occurrence of either P. Brewert or P. glabella m 
Colorado; Rydberg’ merely lists the former as “reported 
from Colorado, but exact locality not given.” There 
are at present two localities in Colorado named Loma, 
neither of them that of the Wheeler Survey. The 
Particular Loma mentioned is apparently 2 cates 
Mexican settlement shown on old survey maps under 
this name, located on the north side of the Rio Grande
