OLEACEZ 
- No. 203. Olea Americana, L.—Devil-wood; American Olive.—South- 
ern States. This isa 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.—Middie 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, Lam.—Red Ash.—Eastern United States. 
A smaller tree than the preceding, perhaps morecommon. The woodis 
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.—Western 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.2—Southern States. Mr. Curtiss 
found at Eufaula, Ala., a large ash with remarkably small fruit. This 
species is provisionally called #. Curtisst. It requires further investi- 
ation. 
; 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.

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.
