98 TREES OF NEW ENGLAND. 



of the tree, the widest spreading of the species, characterized by 

 its dark, hairy buds and rusty -green, dense and rough foliage. 



Bark. Bark of trunk brown and in old trees deeply fur- 

 rowed ; larger branches grayish-brown, somewhat striate ; 

 branchlets grayish-brown, rough, marked with numerous dots, 

 downy; season's shoots light gray and very rough; inner bark 

 mucilaginous, hence the name " slippery elm." 



Winter Buds and Leaves. Buds ovate to rounded-cylin- 

 drical, acute or obtuse, very dark, densely tomentose, very 

 conspicuous just before unfolding. Leaves simple, alternate, 

 4-8 inches long, 3-4 inches wide, thickish, minutely hairy 

 above and woolly beneath when young, at maturity pale rusty- 

 green and very rough both ways upon the upper surface, 

 scarcely less beneath, rough and hairy along the ribs ; sweet- 

 scented when dried ; outline oblong, ovate-oblong, or oval, 

 doubly serrate ; apex acuminate ; base more or less heart- 

 shaped or obtuse, inequilateral ; leafstalk short, rough, hairy ; 

 stipules small, soon falling. 



Inflorescence. March to April. Preceding the leaves, from 

 the lateral buds of the preceding season, in clusters of nearly 

 sessile, purplish flowers ; sterile, fertile, and perfect on the 

 same tree ; calyx 5-9-lobed, downy ; corolla none ; stamens 

 5-9, anthers dark red ; ovary flattened ; styles two, purple, 

 downy. 



Fruit. A samara, winged all round, f inch in diameter, 

 roundish, pubescent over the seed, not fringed, larger than 

 the fruit of U. Americana. 



Horticultural Value. Hardy throughout New England ; 

 does well in various situations, but prefers a light, sandy or 

 gravelly soil near running water ; grows more rapidly than 

 U. Americana, and is less liable to the attacks of insects ; its 

 large foliage and graceful outline make it worthy of a place in 

 ornamental plantations. Propagated from seed.
