branch of the old tree, which had accidentally been used as a pea rod 
by Mr. Holmes, the proprietor of the ground, and was found to be 
growing at the time the parent tree was blown down, so that the 
history of the parent may be remembered by the flourishing of its 
offspring. Another instance of the great size to which this Willow 
grows is given by Hooker in the case of one growing at Gordon 
Castle, Scotland, and which at the age of 61, was fifty-seven feet high, 
and above eleven feet in its greatest circumference. 
Group 5. Albe. Borr. Trees of considerable elevation, having 
lanceolate serrated leaves, with long silky hairs beneath, especially 
in a young state, which give to the foliage a light or whitish hue, 
the serratures glandular. Catkins lax, germens glabrous. 
15 S. al'ba, Linn. (Fig. 1489.) Common White Willow. Stamens 
two; catkins on leafy stalks; capsules ovate, acuminate, nearly 
sessile, smooth ; stigmas nearly sessile, bifid, recurved ; scales short, 
pubescent on the margin; leaves elliptic, lanceolate, regularly glan- 
dulous, serrulated, silky beneath, often so above; stipules lanceolate.

A rapid growing tree, attaining the height of fifty or sixty feet or 
more, with thick cracked bark, and wide spreading branches, downy 
when young. Leaves numerous, lanceolate, broadest above the 
middle, acutely tapering at each end, white, with close pressed silky 
hairs beneath, smooth or slightly silky above, footstalk short, chan- 
neled, the margins regularly serrated, with glandular teeth. Stipules 
small, lanceolate, or roundish, often wanting. Catkins from one to 
two inches long, on lateral branches, bearing several small leaves. 
Scales oblong, obtuse, somewhat hairy and fringed. Stamens with 
long hairy jilaments and yellow two celled anthers Capsule ovate, 
more or less acuminate, nearly sessile, smooth. Stigmas nearly 
sessile, thick, spreading, cleft. 
Habitat —River sides, moist woods, &c,; frequent. 
Tree ; flowering in May. 
From the much more rapid growth of the variety cerulea, and the 
darker colour of the young branches and less hairy leaves, it has 
been thought a distinct species; but these or other characters have 
not been found sufficiently constant to distinguish it as a species, its 
properties seem to be the same. The bark contains so much tanning 
matter as to be used in the North of Europe for tanning leather; the
