Forest Trees of Illinois: How to Know Them

The tulip tree transplants easily, grows rapidly and forms a tall stem.
It is one of the best trees for forest planting on good moist soil. It
can be recommended for roadside planting because it grows tall and has a
deep root system. Where conditions of life are not too severe, it may be
used for shade tree planting.
+PAPAW+ _Asimina triloba_ Dunal
THE papaw, which grows as a small tree or large shrub, is very well
known throughout the State, except in the northern parts, and is
sometimes called the "wild banana" tree. Most commonly it occurs as an
undergrowth in the shade of rich forests of the larger hardwood trees.
Its range extends from New York westward to Iowa and southward to
Florida and eastern Texas. When growing alone, however, it forms dense
clumps on deep, moist soils in creek bottoms. The _bark_ is thin, dark
grayish-brown, and smooth, or slightly fissured on old trees.

The _leaves_ are alternate on the stem, pear-shaped with pointed ends
and tapering bases, smooth and light green above, from 8 to 10 inches
long, clustered toward the ends of the branches.
The dark purple, attractive _flowers_ appear with the leaves singly or
in two's along the branch, measure nearly 2 inches across, and produce
nectar which attracts the bees.
When thoroughly ripe, the _fruit_ is delicious and nutritious. It
measures from 3 to 5 inches in length, turns from greenish-yellow to
very dark brown in color, and holds rounded or elongated seeds which
separate readily from the pulp.
The _wood_ is light, soft or spongy, and weak, greenish to yellowish in
color, and of no commercial importance.
Because of its handsome foliage, attractive flowers and curious fruit,
the papaw has been much used in ornamental planting.
+SASSAFRAS+ _Sassafras albidum_ Nees.
THE sassafras is an aromatic tree, usually not over 40 feet in height or
a foot in diameter in Illinois. It is common throughout the State on dry
soils as far north as La Salle County, and is one of the first
broad-leaf trees to come up on abandoned fields, where the seeds are
dropped by birds. Its range extends from Maine, southern Ontario to Iowa
and south to Florida and west to Texas. In parts of its range it attains
large size.

The _bark_ of the trunk is thick, red-brown and deeply furrowed and that
of the twigs is bright green.
The _leaves_ are very characteristic. It is one of the few trees having
leaves of widely different shape on the same tree, or even on the same
twig. Some are oval and entire, 4 to 6 inches long; others have one
lobe, resembling the thumb on a mitten; while still others are divided
at the outer end into 3 distinct lobes. The young leaves and twigs are
quite mucilaginous.
