Botanical Name : Liquidambar styraciflua
Family: Altingiaceae
Genus: Liquidambar
Species: L. styraciflua
Kingdom: Plantae
Order: Saxifragales
Common Names:American sweetgum or redgum
Habitat :Liquidambar styraciflua is native to warm temperate areas of eastern North America and tropical montane regions of Mexico and Central America.
Liquidambar styraciflua grows in moist to wet woods, tidal swamps, swampy bottomlands, streambanks, and in clearings and old fields or dry-mesic to mesic upland forests, mixed forest edges, rock outcrops. It grows best grows best on rich, moist, alluvial clay and loamy soils of river bottoms
Dscription:
Liquidambar styraciflua is a medium-sized to large tree, growing to 20–35 m (65-115 ft), rarely to 41 m (135 ft) tall, with a trunk up to 2 m (6 ft) in diameter. Trees may live to 400 years.

The leaves usually have five (but sometimes three or seven) sharply pointed palmate lobes. They are 7–19 cm (rarely to 25 cm) long and broad, with a 6–10 cm petiole. The rich dark green, glossy leaves generally turn brilliant orange, red, and purple colors in the autumn.
This autumnal coloring has been characterized as not simply a flame, but a conflagration. Its reds and yellows compare to that of the maples (Acer), and in addition it has the dark purples and smoky browns of the ash (Fraxinus). However, in the northern part of its range, and where planted in yet colder areas, the leaves are often killed by frost while still green. On the other hand, in the extreme southern or tropical parts of its range, some trees are evergreen or semi-evergreen, with negligible fall color.
The male and female inflorescences are separate on the same tree.
The distinctive compound fruit is hard, dry, and globose, 2.5–4 cm in diameter, composed of numerous (40-60) capsules. Each capsule, containing one to two small seeds, has a pair of terminal spikes (for a total of 80-120 spikes). When the fruit opens and the seeds are released, each capsule is associated with a small hole (40-60 of these) in the compound fruit.
Another distinctive feature of the tree is the peculiar appearance of its small branches and twigs. The bark attaches itself to these in plates edgewise instead of laterally, and a piece of the leafless branch with the aid of a little imagination readily takes on a reptilian form; indeed, the tree is sometimes called Alligator-wood
The roots are fibrous; juices are balsamic.
The tree secretes an aromatic fluid, which when processed is called styrax
Additional characteristics of Liquidambar styraciflua include:
*Leaves: Alternate, three to five inches long, three to seven inches broad, lobed, so as to make a star-shaped leaf of five to seven divisions, these divisions acutely pointed, with glandular serrate teeth. The base is truncate or slightly heart-shaped. They come out of the bud plicate, downy, pale green, when full grown are bright green, smooth, shining above, paler beneath. In autumn they vary in color from yellow through crimson to purple. They contain tannin and when bruised give a resinous fragrance. Petioles long, slender, terete. Stipules lanceolate, acute, caducous.

*Flowers: March to May, when leaves are half grown; monoecious, greenish. Staminate flowers in terminal racemes two to three inches long, covered with rusty hairs; the pistillate in a solitary head on a slender peduncle borne in the axil of an upper leaf. Staminate flowers destitute of calyx and corolla, but surrounded by hairy bracts. Stamens indefinite; filaments short; anthers introrse. Pistillate flowers with a two-celled, two-beaked ovary, the carpels produced into a long, recurved, persistent style. The ovaries all more or less cohere and harden in fruit. Ovules many but few mature.
*Fruit: Multicapsular spherical head, an inch to an inch and a half in diameter, hangs on the branches during the winter. The woody capsules are mostly filled with abortive seeds resembling sawdust.
*Bark: Light brown tinged with red, deeply fissured, ridges scaly. Branchlets pithy, many-angled, winged, at first covered with rusty hairs, finally becoming red brown, gray or dark brown.
*Winter buds: Yellow brown, one-fourth of an inch long, acute. The inner scales enlarge with the growing shoot, becoming half an inch long, green tipped with red.

While the starry five-pointed leaves of Liquidambar resemble those of some maples (Acer), such as the Japanese maple (Acer palmatum), the sugar maple (Acer saccharum), and the Norway maple (Acer platanoides), Liquidambar is easily distinguished from Acer by its glossy, leathery leaves that are positioned singly (alternate), not in pairs (opposite) on the stems. The long-stemmed fruit balls of Liquidambar resemble those of the American sycamore or buttonwood (Platanus occidentalis), but are spiny and remain intact after their seeds are dispersed; the softer fruits of Platanus disintegrate upon seed dispersal.
Medicinal Uses:
In Appalachia, water- or whiskey-soaked twigs are chewed to clean the teeth, Native Americans used the resin to treat fevers and wounds. The gum was used by early settlers to treat herpes and skin inflammations. It has also been applied to the cheek to ease toothache. The bark and leaves, boiled in milk or water, have been used to treat diarrhea and dysentery. The boiled leaves have been applied to cuts and used for treating sore feet. The aromatic drug resin storax, an expectorant and a weak antiseptic used for treating scabies, comes from this tree. It forms in cavities of the bark and also exudes naturally. It is harvested in autumn. Production can be stimulated by beating the trunk in the spring. The resin has a wide range of uses including medicinal, incense, perfumery, soap and as an adhesive. It is also chewed and used as a tooth cleaner and to sweeten the breath. It is also chewed in the treatment of sore throats, coughs, asthma, cystitis, dysentery etc. Externally, it is applied to sores, wounds, piles, ringworm, scabies etc. The resin is an ingredient of ‘Friar’s Balsam’, a commercial preparation based on Styrax benzoin that is used to treat colds and skin problems. The mildly astringent inner bark is used in the treatment of diarrhea and childhood cholera.
Other Uses:
Liquidambar styraciflua is valued as a cultivated ornamental tree, and in its natural habitats, as a timber tree and for its dramatically colored fall foliage. The resin for which it was named also has various uses
