The Pitch Pine (pinus Rigida)

Distinguishing characters: Here there are *three* needles to each

cluster, Fig. 4. They are dark, yellowish-green needles about four

inches long. The rough-looking _branches_ of the tree may be seen

_studded with cones_ throughout the year, and _clusters of leaves_

may be seen _sprouting directly from the trunk_ of the tree; see

Fig. 5. The last two are very characteristic and will distinguish

the tree at a glance.

Form and size: It is a low tree of uncertain habit and extremely rough

looking at every stage of its life. It is constantly full of dead

branches and old cones which persist on the tree throughout the


Range: Eastern United States.

Soil and location: Grows in the poorest and sandiest soils where few

other trees will grow. In New Jersey and on Long Island where it is

native, it proves so hardy and persistent that it often forms pure

stands excluding other trees.

Enemies: None of importance.

Value for planting: Well adapted for the sea coast and other exposed

places. It is of extremely uncertain habit and is subject to the

loss of the lower limbs. It frequently presents a certain

picturesqueness of outline, but it could not be used as a specimen

tree on the lawn.

Commercial value: The wood is coarse grained and is used for rough

lumber, fuel, and charcoal.

Other characters: The _fruit_ is a cone one to three

inches long, persistent on the tree for several years.
