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
