A NEW SPEcIEes OF PELLAEA 39 
Hieron.; but a recent examination of a part of Hieron- 
ymus’ type shows S. montanensis to be hardly distinct 
from S. Wallacei, as now understood. That collective 
species is well set apart from S. densa and allied species 
by its laxly cespitose or short trailing stems, its elongate 
ascending, branched, cordlike branches, and its uniform, 
rigidly ascending leaves, these never unequal and secund. 
Habital characters in this group were not well brought 
out by Hieronymus, who had, unfortunately, only very 
scant material at his disposal.

A New Western Species of Pellaea. 
F. K. BUTTERS. 
In 1917, I published in the Fern Journal! some ob- 
servations on Pellaea atropurpurea, P. glabella, and 
certain western forms related to the latter species. 
In that paper, I treated these western forms as varieties 
of P. glabella. After its publication Mr. W. R. Maxon 
called my attention to certain specimens of western 
Pellaeas in the National Herbarium, and very kindly 
sent me all the material of P. glabella and its varieties 
in that herbarium. The results of the study of this 
material, together with a considerable amount in the 
herbarium of the University of Minnesota were embodied 
in an article, which was prepared for publication last 
summer. An unfortunate loss of manuscript has 
necessitated the rewriting of this article, and as it will 
be several months at least before it can be published, 
it seems best to publish in a preliminary note the con- 
clusions reached.
