There are probably a number of species of Japanese and Chinese Chamæcyparis (Retinospora), but till their size, hardiness, and origin have been more fully determined, 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.

CRYPTOMÈRIA.= A genus of evergreens containing only the following species: [Illustration: C. Japónica.] =Cryptomèria Japónica=, Don. (JAPAN CEDAR.) Leaves about ½ 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 ½ to ¾ 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. JUNÍPERUS.= 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, ½ in., in whorls of threes 1. * Leaves smaller; on the old branches mostly opposite 2. [Illustration: J. commùnis.] 1. =Juníperus commùnis=, L. (COMMON JUNIPER.) Leaves rather long, ½ in., linear, awl-shaped, in whorls of threes, prickly-pointed, upper surface glaucous-white, under surface bright green. Fruit globular, ¼ 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 few of them grow tall enough to be considered trees. Var. _Hibernica_ (Irish Juniper) grows erect like a column. Var. _Alpina_ is a low creeping plant. Var. _hemispherica_ is almost like a half-sphere lying on the ground. [Illustration: J. Virginiàna.]
