22 FOREST- TREES OF THE UNITED STATES. 



No. 230. Drypetes crocea, Poir. A small tree of South Florida and the

URTICACE^S. . 



No. 232. Norus rubra, L. Eed Mulberry. Eastern United States. 

 The Ked Mulberry is found throughout the greater part of the United 

 States east of the Mississippi, and also in some of the States west of 

 that river. (Bryant.) It is commonly a smallish tree, sometimes, how- 

 ever, attaining a large size. The berries are quite palatable, are eaten 

 eagerly by birds, and also have a place in the markets as a second-rate 

 fruit. The wood is strong, compact, and extremely durable. 



No. 233. Morns parvifolia. Buck. Small-leaved Mulberry. Texas and 

 westward. 



No. 234. Madura aurantiaca, Nutt. Osage Orange. Arkansas and 

 Southwest. This tree, which is native in Arkansas and Texas, has been 

 quite generally introduced over the country, chiefly from its extensive 

 employment as a hedge-plant. The early French settlers called it Bois 

 d'arc, or Bow-wood, from its use by the Indians for bows. The fruit is 

 of the size and color of a large orange, but is not edible. The wood is 

 very hard, elastic, fine-grained, and durable. 



No. 235. Ficus aurea, Nutt. Gum-tree ; Wild Fig. South Florida. 

 There are many species of wild fig in the West Indies, but this species 

 of South Florida has not been identified with any of them. It is a large 

 tree, full of milky juice, which forms a kind of India rubber, whence it 

 is also called Gum-tree. The fruit is very small and insignificant. 



No. 236. Ficus pedunculata, Willd. Wild Fig. South Florida. This 

 tree is also a native of the West Indies, and, like the Banyan of the 

 West Indies, it sends downward aerial roots, which become fixed in the 

 soil. The fruit is larger than the preceding, being the size of a large 

 cherry. 



No. 237. Ficus Irevifolia, Nutt. Wild Fig. South Florida. 



No. 238. Ulmus Americana, L. White Elm. Eastern United States. 

 One of our most common and valuable trees, very popular as a shade- 

 tree on account of its graceful form. It is one of the largest of the 

 deciduous trees of the United States, attaining sometimes the height of 

 100 feet. The wood is employed for various purposes, but it is not con- 

 sidered durable when exposed to the weather. 



No. 239. Ulmus fulva, Michx. Slippery Elm. Eastern United States. 

 This is usually a smaller tree than the White Elm. It is not as much 

 esteemed as an ornamental tree. The wood, however, is said to be of 

 better quality and more durable. The inner bark is very mucilaginous, 

 and is in extensive use for medical and surgical purposes. 



No. 240. Ulmus racemosa, Thomas. Corky White Elm. Northern 

 States. This tree is limited to the northern portions of the United States, 

 being found sparingly in New England, New York, 'and westward to 

 northern Illinois and Wisconsin. It closely resembles the White Elm, 

 but may be distinguished by the corky wiugs of the smaller branches,, 

 which cause them to look grotesque and rough. Dr. S. H. Wright, of 

 Penn Yan, N. Y., says it grows as rapidly as the White Elm, and he 

 thinks will become as large. He has seen some young trees over two feet 

 in diameter. The wood is tougher and finer-grained than the White 

 Elm. 



No. 241. Ulmus alaia, Michx. Winged Elm. Southern and Western
