1. =Cedrus Libani=, Barr. (CEDAR OF LEBANON.) Leaves 3/4 to 1 in. long,
acuminate, needle-form, rigid, few in a fascicle, deep green in color.
Cones 3 to 5 in. long, oval, obtuse, very persistent, grayish-brown in
color; scales thin, truncate, slightly denticulate; seeds quite large
and irregular in form. A cultivated tree with wide-spreading, whorled,
horizontal branches covered with rough bark. Somewhat tender when young
in the Middle States, but forming a grand tree in proper positions.

2. =Cedrus Atlantica=, Manetti. (MT. ATLAS, SILVER, OR AFRICAN CEDAR.)
Leaves 1/2 to 3/4 in. long, mostly cylindric, straight, rigid, mucronate,
crowded, and of a beautiful glaucous-green color. Cones 2 1/2 to 3 in.
long, ovate, glossy. This beautiful tree has been considered a silvery
variety of Cedrus Libani. They are about alike in hardiness and in
general form. Cedrus Atlantica has more slender branches, denser and
more silvery foliage. From Africa.

5 in. long, ovate, obtuse, very resinous, rich purple when young, and
brown when old; the scales separating from the axis at maturity. Seeds
wedge-shaped, with large, bright brown wings. A beautiful pyramidal
tree, with graceful drooping branches and light silvery foliage. Not

[Illustration: A. imbricata.]

=Araucaria imbricata=, Pavon. (CHILE PINE.) Leaves 1 to 2 in. long,
ovate-lanceolate, sessile, rigid, acute, very persistent, closely
overlapping, completely covering the thick stems, in whorls of 6 to 8,
deep glossy green; branches horizontal, in whorls of 6 to 8, with
ascending tips, covered with resinous, corky bark. Flowers dioecious;
cones (on only a portion of the trees) large, roundish, about 7 in. in
diameter, erect, solitary; seeds wedge-shaped, 1 to 2 in. long. A large,
peculiar, beautiful, conical tree, with much the appearance of a cactus;
not fitted to our climate, although a few specimens may be found growing
quite well near the coast south of Philadelphia. From the mountains of
