LONG SPIKED WILLOW. 
argenteum, the branches are brown, but the twigs are 
hoary with villous hairs. The leaves are very much 
crowded, soft, with whitish shining silky down, so abun- 
dant on either side as wholly to hide the veins, and 
nearly the midrib; they are also nearly without foot- 
stalks, entire on the margin, of a narrow linear outline 
and sharply acute, with a distinct bristly point, H to 2 
inches long, and only about three lines wide. Stipules 
small and linear, seldom seen. The aments come out 
late with the leaves, and the flower branches produce 
from four to seven leaves. The male ament is small 
and narrow, with the scales lanceolate and villous; the 
female aments are oblong, the capsules lanceolate and 
villous. 
The wood of this species, though small, is very white, 
smooth, and close-grained; the species must also be 
hardy, well worth cultivating, and would then probably 
grow to a considerable size. We perceive no affinity 
that this species bears, except perhaps to the S. angusti- 
folia of the borders of the Caspian, from which at the 
same time it is probably very distinct.
