SYLVA AMERICANA. 



extremity of vigorous shoots, and thus display a surface of thirty 

 inches in diameter : whence is derived the name of Umbrella 

 Tree. The flowers open in May or June, and are seven or 

 eight inches in diameter, white, composed of several oblong, 

 concave petals, and situated at the extremity of the branches ; 

 they are beautiful, though less regularly shaped and of a less 

 agreeable odor than those of the other species of magnolia. The 

 conical fruit is four or five inches long, and about two inches in 

 diameter ; it ripens about the first of October, and is of a beautiful 

 rose color, with seeds of a pale red. 



The wood of this tree is soft, porous and unfit for use. The 

 bark on the trunk is gray, smooth and polished : if cut while 

 green, it exhales a disagreeable odor.

The Crab Apple is found 

 on both sides of the moun- 

 tains, except in the state of 

 Maine, Vermont and the 

 upper part of New Hamp- 

 shire. It appears to be most 

 multiplied in the Middle 

 States, and especially in the 

 back parts of Pennsylvania 

 and of Virginia. It abounds 

 above all, in the glades, 

 which is the name of a tract 

 of land fifteen or eighteen 

 miles, on the summit of the 

 Alleghanies. It grows most 

 favorably in cool and moist 

 places, and on fertile soils.
