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 Breadalbaue 

 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. - ,;., i 



The varieties are scarcely distinguishable to my e^'es. 



The only British species with wliich this can be confounded is 

 S. lanata, but that has larger and broader leaves on much ^<horter 

 petioles, which are less dilated at the base, and golden-haired catkins.
