− | Salix alba, Linn. White Willow. Large tree, with short and thick trunk, not excurrent in habit: branches yellowish brown: lvs. ashy gray and silky throughout, giving a white appearance to the whole tree, 2-4 in. long, elliptical. —Heretofore associated with the next species, from which it differs in color of twigs and vesture and color of lvs., as also in its general habit. It is only occasionally seen in Amer. Var. splendens, Anderss. (S. alba var. argentea, Wimm. S. regalis, Hort.). Lvs. densely silky on both sides, nearly silvery-white while young. The forms of this species not easily distinguishable from one another, can be readily distinguished from many other species. | + | Salix alba, Linn. White Willow.
