1. Fraxinus Americana, L. 

 (WHITE ASH.) Leaflets 7 to 9 (usu- 

 ally 7), stalked, ovate or lance-ob- 

 long, pointed, shining above, pale 

 and either smooth or pubescent be- 

 neath, somewhat toothed or entire. 

 Flowers almost always diracious 

 (May), thus the fruit is found on 

 but a portion of the trees. The fruit 

 (August to September) terete and 

 inarginless below, abruptly dilated 

 into the wing, which is 2 to 3 times 

 as long as the terete portion ; entire 

 fruit about 1J^ in. long. A common 

 large forest-tree, 60 to 80 ft. high, F - Americana, 



with gray, furrowed bark, smooth, grayish-green branchlets, and 

 rusty-colored buds. Extensively cultivated. 



2. Frxinus pub6scens, Lam. (RED 

 ASH.) Like the White Ash, but to be dis- 

 tinguished from it by the down on the 

 young, green or olive-green twigs, and on 

 the footstalks and lower surface of the 

 leaves. Fruit acute, 2-edged at base, grad- 

 ually dilated into the wings as in Frax- 

 inus viridis. A smaller and more slender 

 tree than the White Ash ; growing in about 

 the same localities, but rare west of the 

 Alleghanies; heart-wood darker-colored. 



3. Fraxinus viridis, Michx. f. (GREEN 

 F. putescens. ASH.) Smooth throughout; leaflets 5 to 



9, bright green on both sides, ovate or oblong-lanceolate, often wedge- 

 shaped at base and serrate above. Fruit acute and 2-edged or mar-
