midst of the woods. The leaves are of a very 
remarkable shape, being dilated towards the 
summit, like a pear, and armed, when young, 
with 3 or 5 bristle-like points, which fall off 
when the leaf has attained its full size. Fig. 
1594., from Michaux’s Histoire des Chénes, ¥ 
shows these mucros on seedlings of one year’s 
‘and two years’ growth. The leaves are yel- 
lowish, and somewhat downy at their first 
unfolding in spring; but, when fully expanded, 
they become of a dark green above, and rusty 
beneath: they are also thick and leathery in 
their texture. In autumn, they turn of a 
blackish red, and fall with the first frost. The 
acorns (fig. 1566, g) are large, and half-covered 
with very scaly cups. The specific name of 
nigra was given to this oak, by Linnzeus, on’ 
account of the blackness of its bark, and its 1594., @ nigra, 
general dark appearance.
