Spec. Char., §c. A bushy shrub. Leaves alternate, lanceolate, serrated ; 
smooth, glabrous, and shining above; densely clothed beneath with silky 
silvery hairs. Stipules very minute, soon falling off. Catkins of the 
male nearly 1 in. long, slender. Bractea oblong, hairy. Gland obtuse. 
This kind, inits whole form and habit, bears a strong likeness to S. petiolaris 
Smith ; but the silvery silkiness of the old leaves perfectly distinguishes 
it. (Sal. Wob., p. 189.) A native of ? North America; flowering in 
April. Introduced in (?) 1825. A low spreading shrub, with yellowish

shining above ; beautifully silvery-silky beneath; all the leaves of a thin 
texture; midrib pale, prominent, and slightly villous. Footstalks scarcely 
Zin. long. Catkins appearing before the leaves, nearly sessile. Anthers
