]9S Eleventh Annual Repokt 



brown, glabrous or nearly so; leaves ovate to obovate in outline, 

 generally 8-18 cm. (3-7 inches) long, generally truncate at the base, 

 sometimes wedge-shaped, 5-9 lobed, the lobes extending more than 

 half way to the midrib, the middle lobes generally 1}^ or more 

 times as long as the undivided part of the leaf, subtended by these 

 lobes, usually 2-3 times as long, lobes oblong, wedge-shaped or 

 widest at the apex, sinuses variable and rounded at the base, some 

 of the lobes somewhat divided at the apex and ending in several 

 sharp teeth, at maturity bright green, shiny and smooth above, 

 paler or yellow-green and smooth beneath except for tufts of brown 

 hairs in the axils of the primary veins; petioles generally 2-5 cm. 

 (1-2 inches) long; acorns solitary or in pairs, sessile or nearly so; nut 

 ovoid, those of the northern part of the State about 17 mm. (5^ 

 inch) long and nearly as wide, those of the lower Wabash Valley 

 about 21 mm. (^ inch) long and somewhat narrower, reddish- 

 brown, covered more or less with gray hairs, inside of shell densely 

 covered with very pale brown hairs, enclosed for about 1/3 its 

 length in the deeply saucer-shaped cup; cup generally tapering at 

 the base, sometimes rounded or nearly flat; scales blunt, their mar- 

 gins thin, broken, sometimes the end tinged with red, covered or 

 nearly so with gray scales or hairs, giving them a gray woolly ap- 

 pearance. 



Distribution. Iowa and northern Indiana south to Florida and 

 west to Texas. The distribution in Indiana has not been deter- 

 mined. In Wells County it is associated with the red oak and is 

 equally abundant. According to Ridgway and Schneck, it is fre- 

 quent in the lower Wabash bottoms and to a great extent supplants 

 the red oak. It is believed that it is more or less frequent along 

 the Wabash and its tributaries. 



This species so closely resembles Quercus rubra that it is not 

 commonly separated from it. It may generally be distinguished 

 by the leaves being deeper lobed and by its smaller fruit. In Wells 

 County the fruit is generally 3^ smaller than Quercus rubra and 

 nearly the same shape. In the Lower Wabash bottoms it is gen- 

 erally about the same size and somewhat longer. 



The published records of the distribution are as follows: Bar- 

 tholomew (Elrod); Gibson, Knox, Posey and VermiUion (Schneck); 

 Knox (Ridgway). 



Additional records are: Posey and Wells (Deam). 



Economic uses. Wood similar and uses the same as that of the 

 red oak.
