Leaves - simple; alternate; edge lobed (lobes entire). Outline - rounded. Apex - cut almost squarely across, with a shallow hollow, giving a square look to the upper half of the leaf. Base - usually heart-shape. Leaf - three to five inches long and wide; very smooth; with four to six lobes (two lobes at the summit; at the sides two, or two large and two small). Bark - of trunk, dark ash-color and slightly rough. Flowers - four to six inches across, greenish-yellow, marked within with orange, somewhat tulip-like, fragrant solitary. May, June. Found - from Southwestern Vermont to Michigan, southward and westward. Its finest growth is in the valley of the lower Wabash River and along the western slopes of the Alleghany Mountains. General Information - Among the largest and most valuable of the North American Trees. It is usually seventy to one hundred feet high, often much higher, with a straight, clear trunk, that divides rather abruptly at the summit into coarse and straggling branches. The wood is light and soft, straight grained, and easily worked, with the heart wood light yellow or brown, and the thin sap wood nearly white. It is very widely and variously used - for construction, for interior finish, for shingles, in boat-building, for the panels of carriages, especially in the making of wooden pumps and wooden ware of different kings. I asked a carpenter: "Hope, is n't it the tulip wood (which you call poplar*) that the carriage-makers use for their panels?" "Yes, and the reason is, because it shapes so easily. If you take a panel and wet one side, and hold the other side to a hot stove-pipe, the piece will just hub the pipe. It's the best wood there is for panelling." "Of all the trees of North America with deciduous leaves, the tulip tree, next to the buttonwood, attains the amplest dimensions, while the perfect straightness and uniform diameter of its trunk for upwards of forty feet, the more regular disposition of its branches, and the greater richness of its foliage, give it a decided superiority over the buttonwood and entitle it to be considered as one of the most magnificent vegetables of the temperate zone." - Michaux. *The name should be dropped. The tree is not a poplar. The tulip tree was very highly esteemed by the ancients; so much so that in some of their festivals they are said to have honored it by pouring over its roots libations of wine.

It is found farther west and northwest than any other oak of the Atlantic forests. In the prairie region it forms a principal growth of the "Oak Openings." General Information - One of the most valuable and widely distributed oaks in North America, growing sixty to eighty feet in height, or more, with hard, tough wood resembling that of the White Oak. "The most interesting thing about this tree, perhaps is its power, quite unknown in the other White Oaks, of adapting itself to very different climatic conditions, which enables it to live in the humid climate of Maine and Vermont, to flourish in the somewhat drier climate of the Mississippi Valley, and to exist (still farther west) in the driest and most exposed region in habited by any of the Eastern America Oaks." - Sargent. Q. m. olivaformis is a variety found only in a few districts (near Albany and in Pennsylvania), having narrower and rather more deeply lobed leaves.

Leaves - simple; alternate; edge lobed (edge of the lobes mostly entire, but oftenest with a few teeth toward the end). Outline - reverse egg-shape or oval. Base - usually rounded. Ends of the lobes and of the few teeth, sharp and bristle-pointed, especially when young. Leaf - five to eight inches long; three to five inches wide; very variable. The two types, a and b, are often found on the same tree; b is a variation toward the leaf of the Scarlet Oak.

Bark - of trunk, blackish and deeply and roughly furrowed, with an inner bark that is very thick and yellow and bitter. Acorns - variable; usually small; on short stems. Cups - thick; somewhat top-shaped; scales distinct and rather large. . Nut - one half to two thirds of an inch long; rounded; nearly one third covered by the cup. Kernel, bright yellow or orange and bitter. October. Found - from Southern Maine southward and westward. Very common, especially in the Atlantic forests. General Information - A tree fifty to a hundred feet high, with wood that is inferior to that of the White Oak. The yellow inner bark (quercitron of the shops) is a valuable dye, and is rich in tannin. Late in the autumn the leaves turn to a rich yellowish-brown or russet. It is very probable that the "Black Oak" and the "Scarlet Oak" ought to be considered as one, and described, not as species and variety, but as slightly different forms of the single species Q. coccinea. Though the most distinctive leaves of the "Black Oak" are easily recognized, often others are so nearly like those of the "Scarlet Oak" that it is not easy to distinguish between then; and the same is true of the fruit and the bark. Michaux f. says: "The only constant difference between the acorns of the Scarlet Oak and the Black Oak is in the kernel, which is white in the Scarlet Oak and yellow in the Black Oak." The Gray Oak (Q. c., ambigua, Gray) is a variety sometimes found along the northeastern boundary of the States (as far as Lake Champlain) and northward. It combines the foliage of the Red Oak with the acorn of the Scarlet Oak.

Leaves - simple; indeterminate in position because of their closeness; arranged singly all around the branchlets. Leaf - needle-shaped, five twelfths to three fourths of an inch long, four-sided, curved, sharp, rather slender, bluish-green, much lighter than the leaf of the Black Spruce. Bark - lighter than that of the Black Spruce. Cones - one to two inches long, and always in the proportion of about two inches in length to one half or three fourths of an inch in thickness; drooping at the ends of the branchlets; long oval or cylinder-shape; pale green when young, becoming brownish as they ripen. Scales - broad reverse egg-shape, with an entire edge, and rounded or somewhat two-lobed at the apex. Found - in Maine, Northeastern Vermont, Northern Michigan, Minnesota, and far northward, on low ground and in swamps. It is most common north of the United States boundaries.

Branches and branchlets - heavily drooping, especially in the older trees. Scales - broad reverse egg-shape, with an entire edge, and rounded or somewhat two-lobed at the apex. General Information - This spruce is not a native, but is now very widely cultivated, and is sometimes found escaped from cultivation. It is a finer and large tree than the native spruces.

Genus Picea, Link. (Spruce)

Leaves - simple; indeterminate in position because of their closeness; arranged singly all around the…

Leaves - simple; indeterminate, in position because of their closeness; arranged singly in two flat distinctly opposite ranks up and down the branchlets. Leaf - one half inch long, narrow; blunt sometimes minutely toothed toward the apex; flat; green above; silvery white beneath. Bark - reddish and scaly; when old, somewhat roughened by long, shallow furrows. Cones - very small (three fourths of an inch long); drooping; oval or egg-shape. Scales - few, thin, rounded and entire. The seed with the wing is about three fourths the length of the scale. The cone does not fall apart when ripe. Found - from Southern New Brunswick and the Valley of the St. Lawrence through the Northern States to Delaware, and along the Alleghany Mountains to Alabama. Common northward, often forming large forests. General Information - An evergreen tree, sixty to eighty feet high, irregular in outline, very graceful, especially when young, with light and delicate foliage and horizontal or drooping branches. The timber is very coarse; the bark much used for tanning, and with medicinal qualities.

Leaves - Simple; indeterminate in position because of their closeness; arranged singly up and down the branchlets, at first radiating about equally on every side, afterward flattened into two ranks, as in the Hemlock. Leaf - one half to one inch long, narrow; apex blunt or notched; edge entire; flat, with a grooved line above and a corresponding raised line below; bright green above; silvery white below. Bark - smooth and unbroken (especially when young), and usually covered with "blisters." Cones - two to four inches long, one inch broad, erect, at the sides of the branchlets; violet-colored. Scales - thin and flat, broad and rounded. The thin bracts between the scales are tipped with a slender bristle. The cone falls apart when ripe. Found - from the far North through the Northern States to Pennsylvania, and along the Alleghany Mountains to the high peaks of West Virginia. Common northward in damp forests. General Information - A slender, evergreen tree, twenty to sixty feet high; pyramid-shaped, with regular horizontal branches; its wood is very light and soft. From the "blisters," which form under the bark of the trunk and branches, the valuable Canada balsam is obtained. The tree is short-lived, and therefore of less value in cultivation.

Leaves - simple; indeterminate in position because of their closeness; arranged along the branches in many-leaved bunches without sheaths. Leaf - thread-like, one to two inches long, withering and falling in the autumn. Bark - smooth. Cones - about one half inch long; broad egg-shaped; green or violet when young, becoming purple and brownish as they ripen. Scales - thin, nearly round, their edges entire. Found - from Pennsylvania, Northern Indiana, and Northern Illinois through the Northern States and far northward. It grows usually in low, swampy land, where it often thickly covers large areas. General Information - A tree fifty to one hundred feet high (not evergreen), with a straight trunk and slender, horizontal branches. The wood is durable, hard, and very strong, and is largely used in ship-building, for posts, railroad ties, etc. The Indians and Canadians were accustomed to use the fibres of the Larch roots for sewing their bark canoes; and for tightening the seams, the gum of the Balsam Fir. Give me of your roots, O Tamarak! Of your fibrous roots, O Larch-Tree! My canoe to bind together, So to bind the ends together, That the water may not enter, That the river ma not wet me! Give me of your balm, O Fir-Tree! Of your balsam and your resin, So to close the seams together That the water may not enter, That the river may not wet me! And the Fir-Tree tall and sombre, Sobbed through all its robes of darkness, Answered wailing, answered weeping. 'Take my balm, O Hiawatha!'"

Leaves - compound (odd-feathered, but with the odd leaflet often dwarfed or broken off; leaflets, twenty-one to forty-one); alternate; edge of the leaflets entire, with one or two coarse, blunt teeth at each side of their base. Outline - of leaflet, long egg-shape or lance-shape. Apex - taper-pointed. Base, squared, or heart-shaped. Leaf/Stem - smooth, round, swollen at base. Leaflet/Stems - smooth and short. Leaf - one and a half to six feet long. Leaflets variable, usually about six inches by two and a quarter, rather smooth and thin. Bark - of the trunk, smooth and brown; the new shoots marked with whitish dots. Flowers - in long bunches at the ends of the branches; greenish, and of very disagreeable odor. June, July. Seeds - flat, at the centre of greenish and sometimes pink-tinged wings, in large, loose clusters. October. Found - common in cultivation, and to some extent naturalized. General Information - A large, showy tree (sixty to seventy feet high) of remarkable vigorous and rapid growth. It is a native of China. A Jesuit missionary sent its seeds in 1751 to England. In 1784 it was brought from Europe to the United States, and started near Philadelphia. Also about 1804 it was brought to Rhode Island from South America. But the source of most of the trees now found abundantly in the region of New York is Flushing, Long Island, where it was introduced in 1820. It has been a great favorite, and would deserve to be so still were it not for the peculiar and disagreeable odor of its flowers. Ailanthus, from a Greek word meaning "tree of heaven." Ailanthus - This spelling of the name should rule because so given by its author, although, etymologically, Ailantus would be correct, the native Amboyna name being "Aylanto."

Leaves - compound (odd-feathered; leaflets, eleven to twenty-five); alternate; edge entire. Outline - oval or egg-shape. Apex, rounded. Base - rounded. Stem - of leaf, smooth, and covering the leaf-bud of the next year. Leaflets - very smooth, thin, often slightly tipped with the end of the mid-rib. Bark - of trunk, dark, rough, and very deeply ridged. The smaller branches and young trunks are armed with strong, triangular prickles, but these disappear when the parts are three to four inches thick. Flowers - showy and abundant; in long, loose clusters drooping from the sides of the branchlets; white; and very fragrant. May, June. Fruit - a smooth and rather blunt pod, two to three inches long, one and a half inches wide, four- to six-seeded. Seeds, dark brown. September. Found - Native in the Alleghany Mountains from Pennsylvania (Monroe County - Porter) to Georgia; but now very generally naturalized throughout the United States east of the Rocky Mountains. General Information - A tree usually forty to fifty feet high, sometimes ninety feet, and of rapid growth. Its wood is exceedingly hard and strong, and remarkable durable when in contact with the ground. It is used largely for posts, in ship-building, and in turnery, and it is preferred to all other native wood for tree nails. It is one of the most valuable trees of this or of any country. But is cultivation as a timber tree, which at one time was very general, has nearly ceased in the United State on account of the constant damage done by the grub of the Painted Clytus (Clytus pictus). This troublesome borer not only injures the new growth, but also pierces and detaches large branches, leaving the tree ragged and stunted.

Found - in Franklin County, Pennsylvania (Porter), Western New York, westward and southward to Middle Tennessee. Not common. General information - A tree sixty to eighty feet high, or more, with a rather small and regular head. The fewness and the abruptness of its large branches give to it in the winder a dead and stumpy look, whence one of its common names. Its bruised and sweetened leaves are used at the South for poisoning flies. Its seeds were formerly used as a substitute for coffee.

The branches and the trunk, excepting in very young and quite old trees, are usually thickly covered with spines, two to four inches long, which are curved at the base, often two- to three-branches, and of a reddish-brown color. Flowers - small and greenish. Fruit - a long, flat pod (nine to eighteen inches long) reddish; somewhat twisted, and filled between the seeds with a pulp which at first is sweet (whence the name "Honey" Locust) but which soon becomes sour. The seeds are flat, hard, and brown. Found - native in Pennsylvania, westward and southward, but also somewhat naturalized and widely introduced northward. General Information - A tree sometimes seventy feet high, with wide-spreading and graceful branches, and light and delicate foliage. It is often used as a hedge plant. A variety entirely bare of thorns (var. inermis) is sometimes found; also a variety (var. brachycarpos) with shorter fruit and thorns.

General Information - A slender, somewhat pyramid-shaped, tree, ten to thirty feet high, much and justly prized as one of the best of the native trees for ornamental planting. Its bark and the unripe fruit are very astringent, and are sometimes used medicinally. A slightly different species (P. sambucilolia) is sometimes found in cold swamps and on the borders of streams along the Northern frontier. The Mountain Ash or "Rowan Tree" has for a long time been renowned as a safeguard against witches and all evil spirits. A mere twig of it suffices. "Rowen-tree and red thread Put the witches to their speed." "The spells were vain, the hag returned To the queen in sorrowful mood, Crying that witches have no power Where there is row'n-tree wood."

Fruit - round, nearly one and a half to two inches in diameter; the husk, thick (nearly half an inch), depressed at the center, grooved at the seams, and wholly separating into four inches at maturity; the nut, about one inch long, often the same in breadth, slightly flattened at the sides, angular, nearly pointless, whitish, with a rather this shell, and a large finely flavored kernel. October. Found - from the valley of the St. Lawrence River to Southeastern Minnesota, and southward to Western Florida. Its finest growth is west of the Alleghany Mountains. General Information - A tree, fifty to eighty feet high, of great value. Its tough and elastic wood is used in making agricultural implements, carriages, axe-handles, etc. It ranks also among the best of woods for fuel. Most of the "hickory nuts" of the markets are from this species. All the Hickories are picturesque trees. Their tendency, even when standing alone, is to grow high, and with heads that, instead of being round, are cylinder-shaped to the very top, with only enough breaks and irregularities to add to the effect. This tendency is more marked in the Hickories than in any other of the leaf-shedding trees of North America. They are worthy of the name sometimes given them of 'the artist's tree." Hicoria, from a Greek word meaning round, in allusion to the shape of the nut.

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. 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.
