country. Ihave found it in Martha’s Vineyard, in Waltham, 
and along the roads in Berkshire. 
Tue Buiue Witiow, S. certlea, is by some made a separate 
species; by some, it is considered a variety of the white. It is 
figured in Sowerby’s English Botany, p. 2431. The only char- 
acters, by which it is distinguished from S. alba are, that the 
under surface of the leaves is less sulky, often quite smooth, and 
that the leaves have a bluish hue, deeper than that of the white. 
It has been extensively introduced, and is found in many parts 
of the State; and so readily does it propagate itself, that the 
blue willow, with others of the same group, fringes the beauti- 
ful Housatonic, in the midst of wildness and of cultivation, 
from its source to the sea. 
This willow is considered preferable, on account of the rap- 
idity of its growth, to the white.

Figured in Sowerby’s Enghsh Botany, 1889. The tree in Loudon, Arb., 
VIT, Plate 206. 
Leaves lanceolate, acute, with glandular serratures, acuminate, glaucous 
and more or less sulky beneath ; often so, but usually smooth above; stipules 
minute, lanceolate, deciduous, smooth; ovaries ovate-lanceolate, sessile, 
smooth; scales linear-lanceolate, acute, fringed at the base, longer than the 
pistil; style short, stigmas deeply cleft.—Hooker’s British Botany, 419; 
Loudon, Ill, 1528. Dyffers from the white in its longer, more taper aments, 
lanceolate, pointed scales, smooth filaments, smoother leaves, and conspicu- 
ously in its bright yellow branches. 
This is a native of Britain and various other parts of Europe, 
where it is extensively cultivated as an ornamental tree, and as 
an osier, and grows sometimes to the height of fifty or sixty 
feet. 
The golden osier has been more extensively propagated in 
New England than any other foreign willow. It is found in 
many parts of Maine, where it sometimes attains a height of 
thirty feet, in New Hampshire, Vermont, Connecticut, and all 
parts of Massachusetts. As it grows here, the trunk is rarely
