contrast between the two in the character of the seeds; the 
testa in those of R. occidentalis being somewhat coarsely and 
favosely reticulate. 
BERBERIS NANA. Stems very short, mostly simple, usually 
2 or 3 inches, seldom 6, in height, but numerous and elus 
tered from ereeping and branching woody rootstocks: leaves 
long-petioled, the leaflets (in about 3 pairs) oblong-ovate, 
acute, spinulose-serrate, sessile by a broad inequilateral base, 
dull-green and glaucescent on both sides: racemes several, 
terminal (apparently) at flowering, but in fruit lateral: ber- 
ries small, subglobose, blue. 
Plentiful in exposed stony or rocky ground throughout 
the Rocky Mountain region, from Idaho and Montana to 
New Mexico and Arizona; long mistaken for B. repens, 
Lindl., and being certainly the plant to which the name ~ 
repens, as far as that goes, is most applicable. But it is 
equally certain that the present plant is far from that of 
Lindley, whose plate in the Botanical Register, and also the . 
description, represent a stoutish erect branching shrub, not 
unlike B. Aquifolium in size and habit, but differing in form, 
texture, and blue-green hue of the leaflets; also supposed to 
diverge from that species in its mode of propagating itself 
by creeping offshoots. But B. Aquifolium, as I have seen It 
in its native soil, does the same. Quite such a shrub as 
Lindley describes for B. repens is still in cultivation at the 
East; and there are traces of it in the herbaria, such spec! 
mens coming from Idaho and adjacent districts ; and these 
make an approach to B. pumila of California and southern 
Oregon in several particulars.
