THE TilEES OF NORTH CAROLINA. 121 



which character its botanical name of angulata is 

 derived. The wood does not appear to be used. 

 This is very similar to the Cottonwood or Cotton Tree 

 so common on the Western rivers. 



2. Cotton Tree. ' (P. heterophylla, Linn.)— A 

 native of the Middle, Western and Southern States, 

 yet is so rare as to escape general notice. I do not 

 remember to have met with it in this State, except in 

 rich swamp lands on the lower course of the Cape 

 Fear.; but it probably occurs in similar ground else- 

 where. It is a majestic, showy tree, 70 to 80 feet 

 high, 2 to 3 in diameter, with a very thick, deeply 

 furrowed bark. The young branches and shoots are 

 round. The leaves, 3 to 5 inches long, and with 

 rounded teeth, are covered on the underside with a 

 thick soft down, which partially falls off with age. 

 The wood is much like that of the preceding. 



3. Large Toothed Aspen. (P. grandidentata, 

 Michx.) — Not so common in the Southern as in the 

 Middle and Northern States. With us it belongs to 

 the upper part of the Middle District, is about 40 

 feet high, and has a smooth gray bark that seldom 

 cracks. The leaves are 3 to 5 inches long, about the 

 same breadth, with large open teeth on the edges, 

 and the underside clothed when young with a thick 

 white down which wholly falls away before the end 

 of Summer. This tree is occasionally seen adorning 

 the streets of our villages. 



The Lombard?/ Poplar (P. dilatata, Ait.), a native of 

 Italy, is common in cultivation about old settlements.
