along the veins. In the Spring they are hoary and pubescent on both sur- 
faces, which is not the case with either the Q. Coccinea or Q. Rubra— 
Willd. 
With this species I am not well acquainted. The leaves in the figures of 
Abbot resemble very much those of the last variety mentioned under Q. 
Tinctoria, but are hoary from their pubescence. 
Grows in the oak lands of the middle and upper country— a large tree. 
Flowers April.

A large tree 70 — 80 feet high, and 3—4 feet in diameter. Leaves deeply 
sinuate, very glabrous, the sinuses obtuse, the lobes very acute, acutely 
notched and toothed, and mucronate. Petioles 2—4 inches long. Fruit 
very abundant. Nut ovate, oblong, mucronate. Cup turbinate, sessile, en- 
closing about half of the nut. 
This species, which constitutes a large proportion of the oak forests of the 
upper country, is distinguished by the brilliant colour of its leaves towards 
the close of Autumn. Its wood is principajly converted into staves or rails* 1 
or fuel. It is one of the many species to which the name of Red Oak is in- 
discriminately applied. Its leaves are perhaps more dissected than those 
of any other species except the Q. Palustris. 
Grows in the rich oak lands of the upper country. Not common in the 
lower. 
Flowers in April.
