The slippery or red elm (U. fulva, MX.) is a much smaller tree, with larger and more beautiful foliage, and Slippery Elm (Ulmus fulva). soft, downy, rusty-haired buds, whence the name sometimes applied of red elm. Its flow- ers are in lateral clusters ; the samara is larger and with a broader border. The inner bark contains a great quantity of mucilage, of much value in medicine. Michaux considers its wood as superior to that of the white elm. The tree can be readily grafted upon the white American Elm (Ulmus Americana). elm, and if only for ornament it is well worthy of cultivation. The corky white elm ( U. race- mosa, Thomas) has its branches often beset with corky ridges ; its leaves are similar to those of the white elm; its flowers are in racemes ; its wood is tougher and finer grained. The wahoo or winged elm (U. alata, MX.) is a small tree, seldom exceeding 30 feet in height, has a fine-grained, valuable wood, and is to be found in Virginia and southward. The English elm (U. campestris, Linn.) was early introduced into this country, and is a English Elm (Ulmus campestris). stately tree, contrasting finely with the Amer- ican. Its branches, unlike that, tend upward, or else spread more horizontally, and its foliage is of a darker green and more pleasing to the eye. The wych elm {U. montana, Bauhin) has been partially introduced ; it is much cul- tivated in Scotland, and goes by the name of the Scotch elm. It resembles the slippery Wych Elm (Ulmus montana). elm.

Its leaves are obliquely lanceolate, acuminate, sharply serrate ; its fruit is a sort of plum or drupe of a yellowish green color. It has sev- eral varieties, considered by some botanists as distinct species, but probably nothing more
