20 FOREST-TREES OF THE UNITED STATES. 



OLEACE^E. 



No. 203. Olea Americana, L. Devil-wood ; American Olive. South- 

 ern States. This is a small evergreen tree, with thick, leathery leaves, 

 and small, white, fragrant flowers. It is related to the olive-tree of the 

 eastern world, but its fruit has no value. It is impossible to split, and 

 hence the vulgar name of Devil-wood. 



No. 204. Chionanthus Virginica, L. Fringe-tree. Middle and South- 

 ern States. 



No. 205. Fraxinus Americana, L. White Ash. Eastern United States. 

 A large and valuable tree ranging over the eastern portion of the 

 United States. The wood is tough and elastic, and much employed in 

 various manufactures. It is a handsome and ornamental tree. 



No. 206. Fraxinus pubescens,Ij&m. KedAsh. Eastern United States. 

 A smaller tree than the preceding, perhaps more common. The wood is 

 said to be equally as valuable as that of the White Ash. 



No. 207. Fraxinus viridis, Michx. Green Ash. Western States. A 

 middle-sized tree, of vigorous and rapid growth, and the wood has the 

 same qualities as the preceding. 



No. 208. Fraxinus sambucifolia, Lam. Black Ash. Northern and 

 Western States. A large tree, usually growing in moist soil, and hence 

 often called Swamp Ash. The wood is more elastic than that of any 

 other species. It splits easily into thin, narrow strips, which are used 

 for making baskets and hoops for barrels. 



No. 209. Fraxinus quadrangulata, Michx. Blue Ash. W r estern States. 

 This species is not found in the Atlantic States. It is found from 

 Ohio to Wisconsin and southward to Kentucky and Tennessee. It 

 is a large tree, growing from 60 to 70 feet high, with a diameter of 

 2 feet or more. The wood is quite as valuable as that of the White 

 Ash, and is said to be much more durable when exposed to the weather; 

 hence its value for fence-rails, posts, &c. 



No. 210. Fraxiuus platycarpa, Michx. Carolina Water Ash. Southern 

 States. This species grows in swamps or marshy banks of rivers. It is 

 usually 25 or 30 feet high, but sometimes becomes a large tree. The 

 wood is remarkably light and soft, and probably has no economic value. 



No. 211. Fraxinus Curtissi, n. sp.? Southern States. Mr. Curtiss 

 found at Eufaula, Ala., a large ash with remarkably small fruit. This 

 species is provisionally called F. Curtissi. It requires further investi- 

 gation. 



No. 212. Fraxinus Oregona,~Nutt. Oregon Ash. California and Ore- 

 gon. The common ash of the Pacific coast. It grows 60 to 70 feet high. 

 Is of equal value with the White Ash of the Eastern States. 



No. 213. Fraxinus dipetala, H. and A. California Flowering Ash. 

 California and Oregon. 



No. 214. Fraxinus pistacicefolia^ Torr. Texas and westward. 



No. 215. Fraxinus anomala, Torr. Single-leaf Ash. Utah and Ari- 

 zona. This ash is seldom more than a shrub 10 to 15 feet high, growing 

 in ravines among the foot-hills of Southern Utah and Arizona. The 

 leaves are simple, not pinnate, as in the other species. 



No. 216. Fraxinus coriacea, Watson. Thick- leaved Ash. Utah and 

 Arizona. A smallish tree, with thick, leathery leaves, growing in South- 

 ern Utah and Arizona. 



No. 217. Forestiera acuminata, Poir. Southwestern States. A large 

 shrub or small tree, of no economic value.
