Leaves - compound (odd-feathered; leaflets, seven to eleven, usually nine); opposite; edge of leaflet toothed. Outline - of leaflet, narrow, long oval or long egg-shaped Apex - taper-pointed. Base - rounded. Leaf/Stem - lacking. Leaf/Bud - deep blue or blackish. Leaflet - three to five inches long, smooth and green on both sides, excepting where it is slightly hairy along the lower part of the middle rib. When crushed it has an Elder-like odor. Bark - of trunk, dark granite-gray, somewhat furrowed and broken up and down with roughness, which continue in the old tree. The young branches are smooth and grayish and marked with black and white dots and warts. Winged seeds - nearly one and one half inches long, with the wing three eighths of an inch wide and extending around the seed. Ripe in July. Found - along low river-banks and in swamps, which it sometimes fills; in Delaware, the mountains of Virginia, Northwestern Arkansas, through the Northern States to Canada. It is the most Northern of the American Ashes. General Information - Usually a small or medium-sized tree. The wood is largely used for barrel-hoops, baskets, in cabinet-work, and interior finish. Fraxinus from a Greek word meaning "separation," because of the ease with which the wood of the Ash can be split. I find in the notes of an old copy of White's "Natural History of Selborne" this comment: "The Ash, I think, has been termed by Gilpin the Venus of British trees." Gerardes' "Herbal" comments: "The leaves of the Ash are of so great a vertue against serpents, as that the serpents dare not be so bolde as to touch the morning and evening shadowes of the tree, but shunneth them afarre off, as Pliny reporteth in his 16 book, 13 chap. He also affirmeth that the serpent being penned in with boughes laide rounde about, will sooner run into the fire, if any be there, than come neere to the boughes of the Ash." In Scandinavian mythology the great and sacred tree, Yggdrasil, the greatest and most sacred of all trees, which binds together heaven and earth and hell, is an Ash. Its roots spread over the whole earth. Its branches reach above the heavens. Underneath lies a serpent; above is an eagle; a squirrel runs up and down the trunk, trying to breed strife between them.

Found - chiefly along streams and in river bottoms, from Western Vermont to Missouri and Northern Alabama. General Information - A tree fifty to eight feet high or more; of very great value in many directions, - as a shade tree, for fuel, for interior finish and the making of furniture, for its ashes, which give large quantities of potash; especially for its sap, which yields the "maple sugar" of commerce.

Another species, C. speciosa, Ward, larger and of more value, is sometimes met with in Southern Illinois and the adjoining States.

Leaves - simple; opposite; edge entire. Outline - egg-shape, or often broad oval, or reverse egg-shape. Apex - pointed, often taper-pointed. Base - pointed and usually slightly unequal. Leaf/Stem - short (about one half inch). Leaf - three to five inches long; smooth above; pale and nearly smooth beneath; with the whitish ribs very distinct and curved. Bark - of trunk, blackish and rough, with short, broken ridges. The bark, especially of the roots, is very bitter and is used as a tonic. Flowers - The real flowers are greenish-yellow, in a small rounded bunch; but this bunch is surrounded by four large, petal-like leaves, white and often tinged with pink, more than an inch in length, reverse egg-shaped, and ending in a hard, abruptly turned point. The appearance is of a single large flower. The tree blossoms in May before the leaves are fully set. Fruit - The "Flower" is succeeded by a bunch of oval berries that turn bright red as they ripen, making the tree in the autumn, with its richly changing foliage, nearly as attractive as in the spring. Found - in rich woods, from New England to Minnesota, and southward to Florida and Texas. It is very common, especially at the South. General Information - A finely shaped, rather flat-branching tree, usually twelve to thirty feet high, but dwindling, northward, to the dimensions of a shrub; one of the most ornamental of all our native flowering trees. Its character throughout the extent of its range would seem to warrant the recognition of its blossom as the "national flower." Cornus, from a Greek word meaning horn, because of the hardness of the wood.

Found - along borders of streams and in low and swampy ground - New Brunswick to Minnesota, and southward to Northern Florida and Alabama; but rare west of the Alleghany Mountains. Its finest growth is in the Northern Atlantic States. General Information - A medium-sized tree, usually thirty to fifty feet high, of less value than the White Ash. Fraxinus from a Greek word meaning "separation," because of the ease with which the wood of the Ash can be split.

General Information - A tree thirty to sixty feet high, with wood of considerable value, especially when it shows a "curly grain."

Leaves - compound (odd-feathered; leaflets, seven to nine); opposite; edge of leaflets slightly toothed or entire; entire at base. Outline - of leaflet, long oval or long egg-shape. Apex - taper-pointed. Base - somewhat pointed. Leaf/Stem - smooth. Leaflet/Stem - about one fourth of an inch long, or more; smooth. Leaf/Bud - rusty-colored and smooth. Leaflet - two to six inches long; pale beneath; downy when young, but becoming nearly smooth, except on the ribs. Bark - of the trunk, light gray. In very young trees it is nearly smooth, but it soon becomes deeply furrowed - the furrows crossing each other, and so breaking the bark into irregular, somewhat square or lozenge-shaped plates. Then in very old trees it becomes smooth again, from the scaling off of the plates. The branches are smooth and grayish-green. The young shoots have a polished, deep-green bark, marked with white lines or dots. Winged seeds - one and a half to two inches long, with the "wing" about one fourth of an inch wide, hanging in loose clusters from slender stems. The base of the seed it pointed and not winged. Found - in rich woods, from Southern Canada to Northern Florida and westward. It is most common in the Northern States. The finest specimens are seen in the bottom lands of the lower Ohio River basin. General Information - a tree forty to eighty feet high. Often the trunk rises forty feet without branching. Its tough and elastic timer is of very great value, being widely used in the manufacture of agricultural implements, for oars, and the shafts of carriages, and in cabinet-work. Fraxinus from a Greek word meaning "separation," because of the ease with which the wood of the Ash can be split.
