Forest Trees of Texas: How to Know Them
Mattoon, Wilbur R. (Wilbur Reed)
Trees -- Identification; Trees -- Texas
This attractive tree or shrub, may grow as a small tree, sometimes as
much as 30 feet high, with a trunk 6 to 10 inches in diameter. It occurs
in rich, wet woods and on the borders of swamps and streams, but is
adaptable to many sites. It is found in the southeastern portion of
Texas, being a native of the Gulf Region.

natural size; fruit about one-sixth natural size)]
The BARK of the trunk is brown, divided by irregular longitudinal
fissures, and separating on the surface into thin scales. The bark on
the twigs forms long, loose, brown fibers, which makes it easy to
identify during the winter.
The alternate, ovate to obovate LEAVES are bright green above, paler and
downy underneath, 3 to 4 inches long, and 2 to 2½ inches wide. They are
much larger on young shoots. The leaves have minute callous teeth.
The white FLOWERS, usually about 1 inch long, come before the leaves and
are borne in clusters of 3 to 5. The tree is charming when thickly hung
with its “silver bells.” The FRUIT is about 2 inches long with two wide,
thin wings, and two (rarely three) narrow wings in between.
The WOOD is light, soft, strong, close-grained, and light brown, with
thick, lighter-colored sapwood. It is not of commercial importance.
CAROLINA ASH (Water Ash)
Fraxinus caroliniana Mill.
Water ash is common in shaded swamps, westward to the valley of the
Neches River. It forms a tree, rarely more than 40 feet high, with a
trunk sometimes 12 inches in diameter, and has small branches, making a
narrow, often round-topped head.

size; leaf, one-fourth natural size)]
The BARK is thin, light gray, and marked by large irregularly shaped
round patches which separate into small, thin, close scales.
The LEAVES are compounded, 7 to 12 inches long, thick and firm when
mature, with 5 to 7, ovate to oblong, finely to coarsely toothed
leaflets, 3 to 6 inches long, 2 to 3 inches wide, dark green above, and
paler below.
The small male and female FLOWERS appear on separate trees, in February
or March. The FRUIT is elliptic to oblong-ovate, frequently
three-winged, 2 inches long, ⅓ to ¾ inch wide. The wing extends below
the body of the fruit and narrows into a stipitate (stalk-like) base.
The WOOD is light, soft, weak, close-grained, nearly white, sometimes
yellowish, with thick, lighter-colored sapwood. It is used chiefly for
fuel.
WHITE ASH
Fraxinus americana L.
White ash is found in East Texas to the valley of the Trinity River. It
grows best in the rich moist soils of upper bottomlands. The bark is
gray and furrowed, the branchlets smooth and gray with rust-colored
winter buds.
