New and noteworthy Species of Saxifraga. 
By Joun K. SMALL. 
SAXIFRAGA OCCIDENTALIS S. Wats. Proc. Am. Acad. 23: 264. 1888. 
This species was founded on plants collected on Vancouver 
Island, by Prof. Macoun. It is a beautiful and distinct species 
averaging one decimeter in height, with a purple hue which ex- 
tends even to the petals and filaments; it also possesses an abund- 
ance of red or reddish tomentum on the lower surface of the 
finely crenate leaves. This form is not as widely distributed as 
indicated by Dr. Watson, when he states “ the specific name is 
given to the species as the western correlative of the common 
eastern S. Virginiensis,” nor is it the western correlative of the 
latter species, Saxifraga Californica, proposed in the following yeat 
holding that place. Saxifraga occidentalis is apparently confined 
to Vancouver Island and the mainland in the immediate vicinity- 
SAXIFRAGA VIRGINIENSIS Michx. Fl, Bor. Am. 1: 269. 1803. 
Represents one of the most variable and perplexing species t 
the genus Saxifraga, but notwithstanding its variability in habit,size 
and flowers, there are two characters which serve to separate it 
from its relatives in western North America, namely, the triangular 
triangular-ovate or rarely almost lanceolate acute or acutish 
calyx-segments, and the narrowly elliptic or ellipticcapet vale ob- 
tuse or acute (rarely if ever notched) petals.
