Distinguishing characters: The feathery character of the twigs, Fig. 16, and the spire-like form of the tree, Fig. 17, which is taller and more slender than the larch, will distinguish this species from others.

Fig. 18.—Cypress “Knees.”

Leaf: The leaves drop off in October, though the tree is of the cone-bearing kind. In this respect it is like the larch.

Form and size: Tall and pyramidal.

Range: The cypress is a southern tree, but is found under cultivation in parks and on lawns in northern United States.

Soil and location: Grows naturally in swamps, but will also do well in ordinary well-drained, good soil. In its natural habitat it sends out special roots above water. These are known as “cypress knees” (Fig. 18) and serve to provide air to the submerged roots of the tree.

Enemies: None of importance.

Value for planting: An excellent tree for park and lawn planting.

Commercial value: The wood is light, soft, and easily worked. It is used for general construction, interior finish, railroad ties, posts and cooperage.

Other characters: The bark is thin and scaly. The fruit is a cone about an inch in diameter. The general color of the tree is a dull, deep green which, however, turns orange brown in the fall.

Comparisons: The cypress and the larch are apt to be confused, especially in the winter, when the leaves of both have dropped. The cypress is more slender and is taller in form. The leaves of each are very different, as will be seen from the accompanying illustrations.
