FOREST-TREES OF THE UNITED STATES. 23 



States. This species does not grow in the Northern States except on 

 the line of the Ohio River. It is a smallish tree, and has smaller leaves 

 than the other kinds. The branches have a broad and thin corky wing 

 on the opposite sides. The wood is finer-grained and more compact 

 than the White Elm. 



No. 242. Ulmus Floridana, Chap. Florida Elm. Florida. 



No. 243. Ulmus crassifolia, Nutt, Thick-leaved Elin. Texas and 

 Southwest. 



No. 244. Planera aquation, Gmel. Planer-tree. Southern States. 

 This tree is found in the Southern States and in Kentucky and Tennes- 

 see. It is a tree of medium size, with foliage somewhat like that of the 

 European Elm. It is not a common tree, and the wood is not known to 

 be applied to any useful purpose. 



No. 245. Celtis occidentalis, L. Sugar or Hackberry. Eastern United 

 States. This tree is rare in the New England States, but rather common 

 in the southern and western ones. There are several varieties, one ot 

 which is usually a low and straggling bush. In the Western States, it 

 often becomes a lofty tree. It somewhat resembles the elm in foliage 

 and the ash in bark. It produces a dryish kind of berry about the size 

 of a pea. The wood is white, but is not considered durable. 



No. 246. Celtis Mississippiensis, Bosc. Mississippi Hackberry. Mis- 

 sissippi Valley. 



No. 247. Celtis reticulata, Torr. Net-leaved Hackberry. Texas and 

 Southwest. This is a western species, occuring in Texas and the Rocky 

 Mountain region. It is a small tree, often a mere shrub. 



No. 248. Celtis pallida, Torr. Pale-leaved Hackberry. Texas. 



PLATANACE^E. 



No. 249. Platanus occidentalis^ L. Sycamore ; Plane-tree. Eastern 

 United States. This is probably the largest deciduous tree in the United 

 States. It occurs throughout the Eastern, Southern, and Western 

 States, and extends beyond the Mississippi River. In the rich bottom- 

 lands of the western rivers, it sometimes attains the enormous circum- 

 ference of 40 to 45 feet. It much resembles the European Plane-tree, 

 and is thought to possess a richer foliage, and to afford a deeper shade. 

 As a timber-tree it is of little value, as the wood is liable to warp, and 

 decays early. 



No. 250. ^Platanus racemosa, Nutt. California Sycamore. California. 

 This is the sycamore of the Pacific coast, extending from Central Cali- 

 fornia to Mexico. Although a large tree, it does not attain the size of 

 the eastern species. The wood is said to be more valuable, receiving a 

 good polish and being more durable. 



No. 251. Platanus Wrightiana, S. W. Wright's Sycamore. Arizona 



JUGLANDACE^. 



No. 252. Juglans niyra, L. Black Walnut. Eastern United States. 

 This tree occurs in the Atlantic States, but attains its greatest perfection 

 and abundance in the valleys of the Ohio and Mississippi. It has been 

 so much in request for the timber that it is much less common than 

 formerly. The wood is used for the inside finish of houses, for cabinet- 

 work, for gun-stocks, and many other purposes. It produces a nut 

 much like the English walnut, but of stronger oily flavor. They are 

 greatly relished by many persons. 



No. 253. Juglans cinerea, L. Butternut ; White Walnut. Eastern
