6. Quercus Michauxii Nuttall. Cow Oak. Basket Oak. 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. (3^ inch) 

 long; leaves on petioles 1-3 cm. (^-1}^ inches) long, obovate or 

 oval, 7-18 cm. (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, sohtary or in pairs; nut 

 ovoid, 2-3 cm. (l-lj^ 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 pubhshed 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 Linnaeus. Chestnut 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. (J^ inch) long, light brown, scales blunt,
