apparently of this variety, grown in the Horticultural Society’s 
Garden, under the name of Q. alba. In Messrs. Loddiges’s arbo- 
retum is an oak named Q. squamésa, from a specimen of which fig.

appearance, bark, and habit of growth of Q. alba, and as it only 
differs from it in the shape of the leaves, it is doubtless only a vari- 
ation of this variety. 
The American white oak, according to’ Michaux, bears most resemblance to 
Q. pedunculata. The leaves, he says, are regularly and obliquely divided into 
oblong rounded lobes, destitute of points or bristles ; and the indentations are 
the deepest in the most humid soils. Soon after their unfolding, the leaves 
are reddish above, and white and downy beneath ; when fully grown, they are 
smooth, and of a light green on the upper surface, and glaucous underneath. 
In the autumn they change to a bright violet colour. ' Michaux adds that this 
is the only American oak that retains some of its withered leaves till spring. 
The acorns are large, oval, and very sweet; and they are contained in rough, 
shallow, greyish cups. They are borne singly, or in pairs, on long peduncles, 
attached, as in all the species with annual fructification, to the shoots of the 
season. The bark of this species is white (whence the name) and scaly ; 
and on young trees it appears divided into squares, but on old trees into | 
plates laterally attached. The wood is reddish, somewhat resembling that of 
the British oak, but lighter, and less compact. The rate of growth of this
