USA Official State Tree of Louisiana

Bald CypressTree, a state symbol

(Taxodiaceae Taxodium distichum)
Adopted in 1963.

 

Half of Louisiana is timbered with an abundance of varied and beautiful trees, but no action was taken to designate a state tree until 1963 when the bald cypress, Taxodiaceae Taxodium distichum, was made the official tree of Louisiana. The cypress grows in many areas of the state, particularly the swampy areas.

Its shape depends greatly on the amount and duration of flooding in the area, and varies from columnar to conical or bottle shaped. The bark is reddish-brown, fibrous, thin, and divided into small, flat ridges and shallow furrows. Leaves of the cypress tree spread in flat planes in a feathery pattern on its branchlets.

Baldcypress is a deciduous conifer that grows on saturated and seasonally inundated soils of the Southeastern and Gulf Coastal Plains. Two varieties share essentially the same natural range. Variety nutans, commonly called pondcypress, cypress, or black-cypress, grows in shallow ponds and wet areas westward only to southeastern Louisiana. It does not usually grow in river or stream swamps. Variety distichum, commonly called baldcypress, cypress, southern -cypress, swamp-cypress, red-cypress, yellow-cypress, white-cypress, tidewater red-cypress, or gulf-cypress, is more widespread and typical of the species. Its range extends westward into Texas and northward into Illinois and Indiana.

 

Pond cypress is less likely than baldcypress to have knees, and its knees are shorter and more rounded. Its fluted base tends to have rounded rather than sharp ridges and its bark usually is more coarsely ridged (24). Its branchlets are more ascending than those of baldcypress (44), but unfortunately it was given the varietal name nutans (nodding) from observation of a cultivated variation having drooping branches (43). Typical specimens of pondcypress have nearly scale like leaves, which are appressed along the twig in several ranks. Seedlings and fast-growing shoots of pondcypress, however, often have disichous (two-ranked) leaves much like typical baldcypress foliage (39). Despite the usual differences in appearance between the two varieties, not all specimens are typical, and it is often difficult and sometimes impossible to distinguish them (44).

Description:

Leaf: Linear and small, 1/4 to 3/4 inch long, green to yellow-green, generally appearing two-ranked. When growing on deciduous branchlets the leaf-deciduous branchlet structure resembles a feathery pinnately (or bi-pinnately) compound leaf.

Flower: Males in drooping long panicles. Females are subglobose, peltate scales, and tend to occur near the end of branches.

Fruit: Cones are composed of peltate scales forming a woody, brown sphere with rough surfaces, 3/4 to 1 inch in diameter. Cones disintegrate into irregular-shaped seeds.

Twig: May be deciduous or not. Non-deciduous twigs are slender, alternate, brown, rough, with round buds near the end of the twig. Deciduous twigs are two-ranked, resembling pinnately compound leaves.

Bark: Fibrous, red-brown but may be gray where exposed to the weather. Old, thick bark may appear somewhat scaly.
