234 FAMILIAR TREES AND THEIR LEAVES. 



120 feet high. Its sharp-toothed leaflets grow from 

 five to nine on a stem (usually seven, and rarely 

 nine); they are smooth above and below, but some- 

 times tufts of pale hairs will be discovered at the 

 angles of the ribs ; the leaf color is a rich, deep, yel- 

 low green. The fruit has a very thin husk, and is 

 somewhat pear-shaped or else oval; the husk often 

 splits open only at the apex, and falls with the nut to 

 the ground. The kernel is at first sweet, then after- 

 ward bitter. The fruit from which my drawing was 

 made measured scarcely one inch in length ; not in- 

 frequently, however, larger specimens are found.* 



The pignut is distributed from Maine to south- 

 eastern Nebraska, southward to Florida, and along 

 the Gulf States to Kansas and Texas. It is very 

 common on hillsides and dry ridges in all the North- 

 ern States.
