Mountain Laurel.—This is a large shrub, which indifferently bears the name of Mountain Laurel, Laurel, Ivy, and Calico Tree. It abounds in New Jersey and Pennsylvania. Proceeding thence south-west, it is found along the steep banks of all the rivers which rise in the Alleghanies; but it is observed to become less common in following these streams from their source, towards the Ohio and Mississippi on one side, and towards the ocean on the other. It is rare in Kentucky and in West Tennessee, and in the southern states it disappears entirely when the rivers enter the low country, where the pine-barrens commence.
In favorable situations, this shrub grows to the height of eighteen or twenty feet, with a diameter of three inches. The flowers put forth from May to July, are destitute of odor, and disposed in clusters at the extremity of the branches: in general they are of a beautiful rose color, and sometimes of a pure white. They are always numerous, and their brilliant effect is heightened by the richness of the surrounding foliage.
The Palmetto inhabits the southern states, as far north as Cape Hatteras. It is from forty to fifty feet in height, crowned with a tufted summit, which gives it a beautiful and majestic appearance. The Coral Tree is a brilliant and gaudy shrub, native of the open forests of the Carolinas, Georgia, and Florida; it grows to the height of two or three feet. The Snow Berry is an ornamental shrub, inhabiting the banks of the upper Missouri. In the autumn, when the large bunches of ivory or wax-like berries are matured, the appearance is said to be extremely beautiful.
Fruit Trees.—The Chickasaw Plum is common from thirty-four degrees north latitude, to the gulf of Mexico. It is found in great abundance. Prairie plums are found in great quantities on the hazel prairies of Illinois and Missouri. When cultivated under favorable circumstances, the Osage plum is delicious. Crab apple shrubs are found in great quantities in the middle regions of the central valley. Their blossoms resemble those of the cultivated apple tree, and the tree is useful as a stock in which the cultivated apple and pear may be grafted. The Mulberry is rare in the Atlantic states, but abounds in every part of the Mississippi valley. Its wood is valuable, and scarcely less durable than that of the locust.
Vine.—The common grape vine is diffused through all the climates. It frequently happens that we see, in the rich lands, vines of the size of a man’s body, perpendicularly attached at the top to branches sixty or eighty feet from the ground, and at great lateral distance from the trunk of the tree. It is common to puzzle a man first brought into these woods, by asking him to account for the manner in which a vine of prodigious size has been able to rear itself to such a height. There can be no doubt that the vine in this case is coeval with the tree; that the tree, as it grew, supportedthe vine; and that the vine was carried from the trunk with the projection of the lateral branch, until, in the lapse of years, this singular appearance is the result. In many bottoms, half the trees are covered with these vines. In the deep forest, on the hills, in the barrens, in the hazel prairies, and in the pine woods, every form and size of the grape are found.
Of the plants of the winter grape, which so generally clings to the trees in the alluvial forests, probably not one in fifty bears any fruit at all. The fruit when produced is a small circular berry not unlike the wild black cherry. It is austere, sour, and unpleasant, until it has been softened by the winter frosts; but it is said, when fermented by those who have experience in the practice, to make a tolerable wine. The summer grape is found on the rolling barrens and the hazel prairies. It is more than twice the size of the winter grape, is ripe in the first month in autumn, and, when matured under the full influence of the sun, is a pleasant fruit. It grows in the greatest abundance, but is too dry a grape to be pressed for wine. The muscadine grape is seldom seen north of thirty-four degrees. More southerly, it becomes abundant, and is found in the deep alluvial forests, clinging to tall trees. The fruit grows in more scanty clusters than that of other grapes. Like other fruits, they fall as they ripen, and furnish a rich treat to bears and other animals that feed on them; they are of the size of a plum, of a fine purple black, with a thick tough skin, tasting not unlike the rind of an orange; the pulp is deliciously sweet, but is reputed unwholesome. The pine woods grape has a slender, bluish purple vine, that runs on the ground among the grass. It ripens in the month of June; is large, cone-shaped, transparent, with four seeds, reddish purple, and is fine fruit for eating.
Cane.—The Cane grows to the height of twenty or thirty feet on the lower courses of the Mississippi, Arkansas and Red rivers. Its leaves are dagger-shaped, long and narrow, and of a beautiful green. It grows in masses so compact that the smallest sparrow would find it difficult to fly in the intervals. A man could not make his way through a cane brake, at a rate more rapid than three miles a day.
Flax.—A species of flax was found by Lewis and Clarke growing in the valleys of the Rocky mountains, and on the banks of the Missouri. The bark possesses the same kind of tough fibres as the common flax, and the Indians are in the habit of making lint and gun-waddings of it.
Berries.—The gooseberry is indigenous to the United States, and in the western parts grows to great size. The red raspberry is also indigenous. Whortleberries, and blackberries high and creeping, are found in prodigious abundance; many of the prairies are red with strawberries. The cranberry is a native of the country, growing in morasses and rich bottom through its whole extent. Large cranberry swamps occur in New Jersey.
Other Plants.—There are many annual and evergreen creepers in the United States, of various kinds, form and foliage. The grasses are various and luxuriant. In the prairies they are rank and coarse; the Atlantic country is covered with a fine sward. The rush is a useful herbaceous plant, which grows on bottoms of an elevation between that of the cane brakes and the deeply-flooded lands. The pea-vine covers the richer soil of the forest lands; it is small and fibrous. The wild rice is a plant of great importance, found on the marshy margins of the northern lakes,and in the shallow waters of the upper courses of the Mississippi. One of the most striking of the forest productions is the wax-plant, which is nearly entirely of a snow-white, and resembles the most delicate wax preparation. It grows in rich shady woods, and is much prized.
