Leaves oblong-elliptical or oblong-oblanceolate, woolly but soon 
subglabrous above, snow white and woolly beneath. Style shorter 
than the capsule, at first very short. 
On wet rocks and by the sides of streams in the mountains of the 
Scotch Highlands. Not uncommon on the Clova and Breadalbane 
Mountains, Loch-na-gar and Braemar. 
Scotland. Shrub. Early Summer. 
A small shrub, rarely more than 2 or 3 feet high, with rather thick 
chestnut branches, divided into numerous straight twigs. Leaves 1 
to 2 inches long, variable in shape and in the quantity of pubescence, on 
longer stalks than most of the species of the genus, and with these 
stalks much more dilated at the base. The male catkins I have not 
seen; they are said to be produced before the leaves. Female catkins 
1 to 3 inches long, with or without leaves at the base, but never on 
distinct leafy stalks as in the true S. glauca. Catkin-scales brown, 
darker at the top. Germen usually white. The flower-buds are 
large, chestnut colour, and become glabrous long before the catkins 
expand. 
The varieties are scarcely distinguishable to my eyes. 
The only British species with which this can be confounded is 
S. lanata, but that has larger and broader leaves on much shorter 
petioles, which are less dilated at the base, and golden-haired catkins. 
Downy Mountain Willow.
