A tree, 40-60 high, with a trunk rarely exceeding 18'-20' in diameter, stout upright 

 branches forming a compact irregularly shaped head, and slender terete branchlets 

 more or less coated when they first appear with pale pubescence sometimes persist- 

 ent until their second or third year or often disappearing during the first summer, 

 ultimately becoming ashy gray or light brown tinged with red, frequently covered 

 with a glaucous bloom and marked with pale lenticels, and in their first winter by the 

 semicircular leaf-scars displaying a short row of large fibro-vascular bundle-scars. 

 Winter-buds terminal, about i' long, with 3 pairs of scales coated with rufous to- 

 mentum, those of the outer pair acute, rounded on the back, truncate at the apex, and 



rather shorter than those of the other pairs I'-l^' long at maturity and sometimes 

 pinnately cut toward the apex. Bark of the trunk ^-f thick, brown tinged with red, 

 and slightly furrowed, the surface of the ridges separating into thin appressed scales. 

 Wood heavy, hard, rather strong, brittle, coarse-grained, light brown, with thick 

 lighter brown sap wood streaked with yellow; sometimes confounded commercially 

 with the more valuable wood of the White Ash. 



Distribution. Low rich moist soil near the banks of streams and lakes; New 

 Brunswick to southern Ontario, eastern Nebraska and the Black Hills of Dakota, 

 and southward to northern Florida and central Alabama; most common and of its 

 largest size in the north Atlantic states; west of the Alleghanv Mountains smaller and 

 less abundant. Passing into 



Fraxinus Pennsylvanica, var. lanceolata, Sarg. Green Ash. 



Leaves with rather narrower and shorter and usually more sharply serrate leaf- 

 lets lustrous and bright green on both surfaces. 



A round-topped tree, rarely more than 60 high, or with a trunk more than 2 in 

 diameter, slender spreading branches, ashy gray terete glabrous branchlets marked 

 by pale lenticels, and rusty-pubescent bud-scales. 



Distribution. Banks of streams; shores of Lake Champlain through the Appa- 

 lachian region to western Florida, and west to the valley of the Saskatchewan, the 

 valley of the Colorado River, Texas, the eastern ranges of the Rocky Mountains, the 

 Wasatch Range, Utah, and the mountains of eastern and northern Arizona; com- 

 paratively rare east of the Alleghany Mountains; most abundant in the Mississippi
