It no doubt was an occasional tree along the Ohio River up to Dearborn County. It has also been reported by Aiken for Hamilton County, Ohio. In the Lower Wabash Valley it is associated with Spanish and pin oak. =Remarks.=--Wood and uses similar to white oak. In the flats of southeastern Indiana it is generally called white oak, and in some places it is known as bur oak. It grows very rapidly and to a large size. A tree was measured in 1919 in the Klein woods about 4 miles north of North Vernon that was 3.57 meters (11 feet, 7 inches) in circumference, breast high, and was estimated to be 15 m. (50 feet) to the first branch. This species when grown in the open forms a large oval head, and in moist soil would make one of the best shade and roadside trees to be had. It is not known how it would adapt itself to high ground, but it is believed this species is worthy a trial as a shade tree. It is apparently hardy in the northern counties. =Quercus Bèadlei= Trelease. (_Quercus alba × Michauxii_). This hybrid between the white and cow oak was found by the writer in 1913 in the White River bottoms 3 miles east of Medora in Jackson County. The tree measured 3.54 meters (139 inches) in circumference breast high. Specimens were distributed under No. 19,037, and the determination was made by William Trelease, our leading authority on oaks. =5.= =Quercus Prìnus= Linnæus. (_Quercus montana_ Willdenow of some recent authors). Chestnut Oak. Plate 44. Medium to large sized tree; bark dark, tight, deeply fissured, the furrows wide, and the ridges continuous; leaves on petioles 1-3 cm. long, 1-2 dm. long, obovate to lanceolate, those growing in the shade usually the widest, rounded at the base, usually narrowly so or even wedge-shaped, short or long taper-pointed at the apex, the apex blunt, margins coarsely and nearly regularly crenate-toothed, the teeth broad and rounded, dark green above at maturity, a lighter and usually a yellow or grayish green beneath, only slightly hairy above when young, soon becoming entirely glabrate, very pubescent beneath when young and usually remaining so until maturity; petioles, midrib and primary veins beneath are usually conspicuously yellow, which is a distinctive character of this species; acorns solitary or in pairs, on short stalks usually about 1 cm. long, sometimes sessile; nuts large ovoid or oblong-ovoid, 2-3 cm. long, enclosed generally for about 1/3 their length in a thin cup; scales with triangular blunt tips, generally somewhat tuberculate and pubescent on the back; kernel sweet.
