it would be impossible to make an
entirely satisfactory list for such a work as this. Figures are given of
the common, so-called, species cultivated in this country; under each of
these, several varieties are sold by the nurserymen. The three twigs of
Retinospora squarrosa were all taken from a single branch; this shows
how impossible it is to determine the varieties or species; the twig at
the left represents the true _squarrosa_; the others, the partial return
to the original. Most of the forms shown in the figures have purple,
golden, silvery, and other colored varieties.

GENUS =105. CRYPTOMERIA.=

A genus of evergreens containing only the following species:

[Illustration: C. Japonica.]

=Cryptomeria Japonica=, Don. (JAPAN CEDAR.) Leaves about 1/2 in. long, not
flattened, but about equally 4-sided, curved and tapering quite
gradually from the tip to the large, sessile base; branches spreading,
mostly horizontal, with numerous branchlets. Cones 1/2 to 3/4 in. in
diameter, globular, terminal, sessile, very persistent, with numerous,
loose, not overlapping scales. A beautiful tree from Japan, 50 to 100
ft. high. Not very successfully grown in our climate. North of
Washington, D. C., it needs a sheltered position, and should have a
deep, but not very rich soil.

GENUS =106. JUNIPERUS.=

Leaves evergreen, awl-shaped or scale-like, rigid, often of two shapes
on the same plant. Spray not 2-ranked. Flowers usually dioecious.
Fertile catkins rounded, of 3 to 6 fleshy, coalescent scales, forming in
fruit a bluish-black berry with a whitish bloom, but found on only a
portion of the plants.

* Leaves rather long, 1/2 in., in whorls of threes 1.

* Leaves smaller; on the old branches mostly opposite 2.

[Illustration: J. communis.]

1. =Juniperus communis=, L. (COMMON JUNIPER.) Leaves rather long, 1/2 in.,
linear, awl-shaped, in whorls of threes, prickly-pointed, upper surface
glaucous-white, under surface bright green. Fruit globular, 1/4 in. or
more in diameter, dark purple when ripe, covered with light-colored
bloom. A shrub or small tree with spreading or pendulous branches;
common in dry, sterile soils. There are a great many varieties of this
species in cultivation, but
