differs from the red oak in that it usually grows in dry soil, has the 
leaves deeper lobed, acorn about half the size and with a deeper 
cup. 
The published records of the distribution are as follows: Cass 
(Coulter); Clark (Smith); Delaware, Jay, Randolph and Wayne 
(Phinney) ; Franklin (Meyncke); Gibson (Schneck) ; Jefferson (Coul- 
ter) and (Young); Knox (Ridgway)*; Kosciusko (Clark); Miami 
(Gorby); Noble (Van Gorder); Posey (Schneck); Vigo (Blatchley). 
Additional records are: Clark (Deam); Putnam (Grimes); Tippe- 
canoe (Coulter). 
Economic uses. Wood similar to the red oak though not so 
valuable. 
13. Quercus ellipsoidalis KE. J. Hill. Pry Oax. Plate 56. Bark 
on the trunk a gray or dark brown, fissured, inner layers yellow; 
branchlets at first hairy, becoming smooth and a grayish or reddish- 
brown; winter buds ovate, taper pointed, about 5 mm. (% inch) 
long, reddish-brown, scales more or less hairy with ciliate margins; 
leaves oval to nearly orbicular or obovate in outline, 7-15 em. (3-6 
inches) long, truncate or wedge-shape at the base, 5-7 lobed, usually 
7-lobed, the terminal lobe oblong to triangular, the lateral lobes 
usually narrowed at their base, sinuses deep and rounded, leaves 
hairy when they unfold, becoming at maturity thin, smooth and a 
bright green above, paler and glabrous beneath, except that the 
axils of the principal veins have tufts of brown hairs, petioles 
usually smooth, 2.5-5 em. (1-2 inches) long; acorns sessile or 
nearly so, solitary or in pairs; nut depressed oval or oblong, 1.5-2 
em. (14-34 inch) long, more or less hairy, especially toward the 
base, enclosed from 1/3 to 1% its length by the cup; cup cup- 
shaped, tapering at the base, slightly pubescent within; scales 
rather blunt, slightly hairy; kernel yellow and bitter. 
Distribution. Northwestern Indiana and southern Wisconsin 
west to eastern Iowa and southeastern Minnesota. In Indiana it 
has been reported from Lake County only. Specimens taken near 
Liverpool, Lake County, by Rev. E. J. Hill, are in the Deam herbar- 
ium. In its range it has been commonly mistaken for the pin oak 
(Quercus palustris) which it closely resembles. 
Commonly found on dry or upland ground, although it grows in 
moist or wet soils. Of the bristle tipped oaks, it is most frequently 
associated with the red and scarlet oaks. 
*Quercus Schneckii Britton.
