orange and scarlet before falling, about 4 in. long and 2 in. broad, obovate or ovate, 

 acute at the apex, cuneate at the base ; with four to seven pairs of acute or rounded 

 teeth ; lateral nerves five to eight pairs ; upper surface dark green, with scattered 

 glandular hairs ; lower surface pale, with scattered minute pubescence ; petiole 

 glabrous, to in. long. 



Fruit ripening in the first year, clustered, sessile ; acorn edible, ovoid, \ to f in. 

 long, white pubescent and rounded at the apex, enclosed for half its length in a 

 hemispherical cupule, pubescent within, and covered with grey tomentose scales, 

 large and thickened in the lower ranks, thin and forming a fringe-like rim at the 

 upper margin of the cupule. 



This is usually a low shrub, spreading by root suckers, and growing on rocky 

 slopes and hill-sides. It is distributed from Massachusetts to North Carolina, 

 extending westward to Nebraska, Kansas, Indian Territory, and eastern Texas, 

 where it is often seen on the low undulating prairies. 



It was introduced in 1823, but is very rare in cultivation, the only specimens 

 which we have seen being at Kew and Tortworth, where it does not appear to 

 bear fruit. (A. H.)
