116 SILVA OF NORTH AMERICA. SALICACE. 
usually white on the lower surface and often seven or eight inches in length, in its more glandular 
petioles and the rather narrower and less hairy scales of its pistillate aments. Another variety, Salix 
lasiandra, var. caudata,’ is distinguished by its thicker and more coriaceous usually smaller and often 
more or less faleate leaves wedge-shaped at the base and green on both surfaces, by its much thicker 
and more densely flowered staminate aments, with scales generally dentate near the apex only, by its 
yellow branchlets, its larger buds often villous, especially below the middle, and its smaller size. 
Salix lasiandra is a common inhabitant of river banks and the shores of lakes in California west 
of the Sierra Nevada. In western Oregon, Washington, and southern British Columbia, where it ranges 
as far north, at least, as the Selkirk Mountains,’ it is often replaced by the variety Lyallit, which is 
one of the most beautiful of the American Willows, and in western Oregon and Washington one of the 
commonest trees on river banks and in other low and moist situations, its tall stems often growing in 
clusters ; and in the interior of the continent by the variety caudata, which is distributed from the 
Sierras of northern California to northern Montana, Colorado, and northern New Mexico. 
The wood of Salix lasiandra is light, soft, brittle, and not strong ; it contains numerous obscure 
medullary rays, and is light brown, with thick lighter colored or often nearly white sapwood. The 
specific gravity of the absolutely dry wood is 0.4756, a cubic foot weighing 29.64 pounds. The specific 
gravity of the variety Lyallii is 0.4547, a cubic foot weighing 28.34 pounds. The wood of the variety 
caudata is rather darker, with light brown sapwood; its specific gravity is 0.4598, a cubic foot 
weighing 28.65 pounds.
