| The laurel family includes about 45 genera and 1,000 species of plants, the majority of which are evergreen. While most of the trees of this family are tropical, a few extend into the Temperate Zones. Three plants with arborescent forms of this family are common in Florida. |

camphor tree |
Habit
The camphor tree is native to Asia but has been widely planted in the south as an ornamental and shade tree and is commonly naturalized. Its potentially large trunk is short and rises into several large, ascending branches, which form a crown of dense, attractive foliage. Leaves Leaves are simple, alternate, and persistent. The leaves are 2-3
inches long, 1/2-2 inches wide, oval-shaped, and taper into an acute apex.
Leaf bases are wedge-shaped or rounded. Leaf margins are entire.
Leaf surfaces are bright green and lustrous above, duller and slightly
grayish-green below. Leaf petioles are shorter than the blades.
The leaf blades are somewhat leathery when mature.
The twigs green or green suffused with red and glabrous.
The bark is smooth and gray to gray-brown.
The camphor tree is naturalized in vacant lots, along fence and hedge
rows, and in various mixtures of upland hardwoods. It is found throughout
northern Florida, southern Georgia, and southern Alabama.
An aromatic substance in the leaves, stems, roots, and fruits of the
camphor tree have been commercially used in the manufacture of medicinal
remedies.

redbay |
| Habit
The redbay is an attractive evergreen tree, sometimes reaching 60-70
feet in height, 2-3 feet in diameter. In the forest it develops a
clear, cylindrical bole and a dense, pyramidal crown with ascending branches.
The fleshy, yellowish roots are deep and widespread.
Leaves are simple, alternate, and persistent. The leaves are 3-4
inches long, 1-1.5 inches wide, oval to elliptical-shaped, with a rounded
or acute apex. Leaf bases are broadly wedge-shaped or rounded.
Leaf margins are entire, thickened and curl under. Leaf surfaces
are bright green and lustrous above, paler with a waxy layer below.
Leaf petioles are stout, rigid, grooved above, red-brown, about 1/2 inch
long.
The twigs are slender, those of the current season are 3-angled and
are somewhat fluted, light brown, and glabrous except for a coating of
pale or rusty-red pubescence when they first appear. The pith is
whitish, rounded, and homogeneous.
The bark is reddish-brown and divided by deep, irregular fissures into broad, flat, superficially scaly ridges. If you scrape off some of the bark surface of this tree, you will find a reddish-brown layer underneath. This is a distinguishing characteristic. Habitat The red bay grows on rich, moist soils along streams and borders of
swamps in association with both conifers and hardwoods. It occasionally
appears on dry, sandy soils in association with longleaf pine. It
is found on the Atlantic and Gulf coastal plains from Delaware to eastern
Texas; north through Louisiana to southern Arkansas; also in southern Florida.
This tree is known to many because of its aromatic leaves, which are
the "bay leaves" used to season sauces and soups. The wood is used
in cabinetry and in interior finishing. It was employed in boat construction
at one time.

swampbay |
| Habit
The swampbay is small evergreen tree, reaching 30-40 feet in height,
10-15 inches in diameter. In the forest it develops a clear, cylindrical
bole and a dense, pyramidal crown with ascending branches. The fleshy,
yellowish roots are deep and widespread.
Leaves Leaves are simple, alternate, and persistent. The leaves are 3-4
inches long, 1-1.5 inches wide, oval to elliptical-shaped, with a rounded
or acute apex. Leaf bases are broadly wedge-shaped or rounded.
Leaf margins are entire, thickened and curl under. Leaf surfaces
are bright green and lustrous above, paler with rusty red hairs below.
These hairs are a key distinguishing factor between this tree and the redbay.
Leaf petioles are stout, rigid, grooved above, red-brown, about 1/2 inch
long.
The twigs are slender, those of the current season are 3-angled and are somewhat fluted, light brown, and with dense pubescence. The pith is whitish, rounded, and homogeneous. Bark The bark is brown and divided by deep, irregular fissures into broad,
flat, superficially scaly ridges.
The swampbay frequents pine-barren swamps and river bottoms along the
Atlantic and Gulf coastal plains from southern Virginia to southern Louisiana.
This tree also has aromatic leaves, similar to those of redbay but more
subtle.
