In the size and form of the leaves, this resembles .S. atra. 
The leaves are, however, less inclined to turn back, and re- 
semble much those of Vacecnzum uliginosum. The catkin is 
looser than in .S. a¢va and the capsule much larger and less 
villous. The following specimens belong here: 
Anticosti: Ellis Bay, 1883, AZacoun (18830, type). 
Hupson Bay: Diggs Island, 1884 (z28820* and 18825); 
Mansfield Island, (78879? and 28820"). 
Lasrapvor: Ford’s Harbor, 1884, A. Bell (78819') ; Cape 
Chudley (78879*).

It differs from the preceding by its broadly obovate obtuse 
bright green leaves. As it is a much lower plant with more 
depressed stems, it might have been placed nearest to S. pef- 
rophila which it resembles in the color and texture of the 
leaves. From that species it is easily distinguished by the 
small broad leaves and the short petioles.

Laprapor: Nachhak, 1884, A. Bell (18879°).

This represents S. g/auca in the Rocky Mountains. It 
differs in the shorter capsule, the darker, fuscous and acutish 
bracts and the denser pubescence of the leaves. In age, the 
leaves, however, often become glabrous (var. glabrescens 
Anders.) ; this is especially the case at high altitudes, and as 
it then is very low it has been mistaken for S. anglorum 
OS. Brownri Lundst.), which is an arctic species. At lower 
altitudes it becomes a taller shrub, often 1 m. high, and 
would then scarcely be classified among the cespitose wil- 
lows. Specimens with mature leaves much resemble |S. chlo- 
rophylla; it scarcely differs indeed from that species except 
by the fact that in .S. e/aucops the catkins are at the end of
