( 261 ) 
from Labrador, collected by Rev. A. C. Waghorne, no. 
2, 1893; one from Silver City in the Rocky Mountains, col- 
lected by A/ucoun, 1885 (Herb. Geol. Surv. Can., no. 18849), 
and one from the Rockies in the Herb. Hooker, Barrett and 
Torrey, no. 86. The first is most like the European form, 
differing only in the less pubescent bracts. The second has 
smaller leaves, short catkins and truncate bracts. It forms 
a connecting link with S. savémontana and S. nivalis. 
4. SALIX SAXIMONTANA. Salix reticulata Bebb, in Coulter, 
Man. R. M. 339. Not L. 
Densely cespitose and intricately branched; whole plant 
seldom more than 5 cm. above ground; bark of the older stems 
brown, of the young branches light yellow, glabrous and 
ini bud-scales brown or yellow, perfectly glabrous; 
leaves light green above, glaucous beneath, on both surfaces 
perfectly” glabrous and shining, rather strongly veined and 
somewhat reticulate beneath, but less so than in the two pre- 
ceding ; petiole about 1 cm. long ; leaf-blade 1-2 cm. long, ob- 
long or elliptic-oblong, commonly acutish at both ends; catkin 
1-2 cm. long, somewhat loosely many-flowered; bracts ob- 
long, cuneate, truncate, light yellow, almost perfectly gla- 
brous ; ovary conical, sessile, densely and finely white-tomen- 
tose, with a nearly sessile stigma; filaments glabrous or 
with a few long hairs on the lower portion. 
This species includes all specimens that have been named 
S. reticulata from the Rocky Mountains within the United 
States. It differs from the European S. re¢‘eu/ata in the 
narrower, more acute, lighter green and less reticulate leaves, 
the glabrous bracts and almost glabrous filaments. In Mon- 
tana it seems to grade into S. wzvalis. The following speci- 
mens belong here:
