6. Quercus Michaixii Nuttall. Cow Oak. BaskerOax. Plate 
49. Bark gray, flaky; twigs stout, dark green and hairy, soon be- 
coming smooth, reddish-brown and finally gray; winter buds ovoid 
or oval, acute, reddish, somewhat hairy, about 6 mm. (14 inch) 
long; leaves on petioles 1-3 cm. (24-114 inches) long, obovate or 
oval, 7-18 em. (3-8 inches) long, short taper-pointed at the apex, 
wedge-shaped or narrowly rounded at the base, margin coarsely 
and deeply toothed, the teeth rounded, leaves hairy on both sur- 
faces when they unfold, at maturity becoming firm, smooth and 
dark green above, paler beneath and remaining densely covered with 
whitish hairs; acorns sessile or nearly so, solitary or in pairs; nut 
ovoid, 2-3 em. (1-114 inches) long, hairy at the apex, enclosed for 
about half its length by the thick and deeply cup-shaped cup which 
is somewhat flat at the base and pubescent within; scales mostly 
acute, pubescent and much thickened on the outer face. 
Distribution. Delaware south to Florida and west to Missouri 
and Texas. In Indiana it is found only in a few counties along 
the lower Wabash. Robert Ridgway says it is common in rich 
bottom lands along the lower Wabash. In size and habit it much 
resembles the swamp white oak for which it is often mistaken. 
The published records of the distribution are as follows: Gib- 
son (Ridgway); Knox (Ridgway) and (Thomas). 
Additional records are: Gibson (Schneck). 
Economic uses. Wood similar to the white oak and the supply 
so limited as to be of little commercial importance. 
7. Quercus Prinus Linneus. CHrestnut Oak. TANBARK Oak. 
Plate 50. Bark on the trunk, deeply fissured, the furrows wide 
and ridges continuous, dark gray brown or nearly black, smooth on 
the small branches; twigs purplish green, usually nearly smooth, 
turning to a gray, reddish or dark brown; winter buds ovate, taper- 
pointed, about 7 mm. (14 inch) long, light brown. scales blunt,
