hat 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-cylindrical, 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, 3/4 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.
