MONOECIA POLYANDRIA. 
609 
A large and magnificent tree, growing 70 — 80 feet in height, and 2 — 5 or 
6 feet in diameter, with a shaft frequently 40—50 feet without branches, and 
a fine regular head. Leaves large, on petioles about an inch long, obovate 
or frequently oblong-lanceolate, regularly, equally and obtusely toothed, gla- 
brous on the upper surface, slightly pubescent underneath. Fruit very 
abundant. Nut large, ovate. Cup nearly hemispherical, inclosing about 
one-third of the acorn, on short peduncles. 
This tree grows in the same soil and situation as the Q. Alba. In the low 
country it is more abundant, and generally attains a large size than the 
White Oak. Its timber, though perhaps inferior, is generally employed in- 
discriminately with that species with which even in name it is often con- 
founded. Swamp Chesnut Oak. 
Flowers in April.

A large tree found intermingled with the two preceding species. The 
leaves are more irregularly toothed, more obtuse at base, (sometimes slight- 
ly cordate) and much more tomentose and soft underneath, than those of the 
Q. Prinus; and the acorn, judging from my own specimens, are larger than 
those of Q. Macrocarpa. 
The Q. Yelutina of Mr. Kin seems to belong to this species. 
Grows in rich flat lands and along the margins of swamps. 
Flowers April. 
Leaves on petioles, 
obovate, obtuse at 
base, unequally tooth- 
ed and sinuate, tomen- 
tose underneath; fruit 
generally in pairs; nut 
very large, ovate.
