1. U. America'na. 



Leaves ovate, acuminate, serrate, unequal at the base; foicers pedioelled ; 

 fruit fimbriate. This majestic tree is common in the Northern, Middle and 

 Western States. It is a native of the forest, but often grows spontaneously 

 in open fields, where it is readily distinguished by its long, pendulous 

 brandies. The trunk, with a diameter of 3 — 5 feet, towers to the hight of 30, 

 50, and even 70 feet, perfectly straiglit and naked, when it divides into 2 or 

 more primary branches. These ascend, gradually spreading, and repeatedly 

 dividing into other long, flexible limbs bending in broad, graceful curves. It 

 is a ffreat favorite as a shade tree, and is frequently seen rearing its stately 

 form ^and casting its deep shade over the " sweet homes" of JNew-Engiand. 

 Leaves siiort-sralked, oval-acuminate, doubly denticulate, and 4—5 inches 

 long. The ribs are quite regular and prominent. Flowers small, purplish, 

 collected into small, terminal clusters, and appearing in April, before the 

 leaves. Fruit flat, fringed with a dense down. The wood is tough and strong, 

 but not easily wrought ; used for the naves of wheels, &c. White Elm.
