Obs. Collected, in the above locality, by Mr. Joshua Hoopes. There seems to 

 be some varieties of this, also,— whilst they all bear a considerable general 

 resemblance to the two following species. Indeed, the elder Michaux made all 

 the species of this subdivision mere varieties of the Q. Prinus. 



10. Q. mostana, Wilhl. Leaves broad-obovate, acute, pubescent and 

 gubglaucous beneath, coarsely and nearly equally dentate, the teeth 

 short, broad and obtuse, submucronate; fruit on short peduncles; cup 

 guh-turbinate ; nut elliptic-oblong. Beck, Bot. p. 331.

 branches,— when old, the bark thick, and deeply furrowed. Leaves 4 or 5 to 8 

 or 9 inches long, and 3 to 5 or 6 inches wide, broadly (and sometimes roundish-) 

 obovate, acute, obtusely sinuate- or repand-dentate, the teeth broad, short and 

 obtuse, but often mucronate with a small callous point, the base of the leaf cun«i- 

 ate, or often obtuse, and unequal, the upper surface smooth, the under surface 

 finely pubescent, and paler, or often bluish-glaucous ; petioles half an inch to near 

 an inch long. Acorn large (about an inch and quarter long, and 2 thirds of an 

 inch in diameter), elliptic- or ovoid-oblong, in a rather deep bowl-shaped, or sub- 

 lurbinate, squamose cup, which embraces nearly 1 third of the acorn, and it 

 sealed on a short peduncle. 

 Uab. Hilly? rocky woodlands : frequent. Fl. May. Fr. October. 



Obs. The tcood of this is valuable ; and the bark highly esteemed by the Tan- 

 ners. The acornst also, are sweet and nutritious.

 bescent and cinereous beneath, nearly equally dentate, the teeth rather 

 acute, callous at apex ; cup hemispherical ; nut roundish-ovoid. Beck,
