 a large tree; but, in the fertile lands in the State of Alabama, it attains a 

 great size. ' 



Grows in moist or gravelly clay soils.

A large tree attaining the height of 60—70 feet, and a diameter of 2—4, 

 With branches somewhat regular, and a head of dense and handsome foliage. 

 Leaves long, irregularly and lyrately sinuate, the lower lobes generally acute 

 "le upper obtuse and sometimes emarginate, glabrous on both surfaces' 

 "early sessile. Nut of a middling size, almost globular, covered excepting 

 Its mucronate summit, with its scaly cup: ^ 

 duncle. 



The timber of this tree is said by Michaux to be valuable, but inferior to 

 [he White Oak. It is, in fact, so circumscribed in its habitat, that it is but 

 Wtle used or known. Over Cup Oak. 



Grows almost exclusively in the rich swamps that border our large rivers. 

 % no means rare in its native habitations. 



Flowers April.
