3. Chamæcýparis Lawsoniàna, Park. (Lawson's Cypress.) Leaves small, deep green, with a whitish margin when young, forming with the twigs feathery-like, flat spray of a bluish-green color; leaves usually with a gland on the back. Cones scarcely ¼ in. in diameter, of 8 to 10 scales. A magnificent tree in California, and where it is hardy (in rather moist soil, New York and south) it forms one of our best cultivated evergreens. The leading shoot when young is pendulous.
R. obtùsa.
4. Chamæcýparis (Retinóspora) obtùsa, Endl. (Japanese Arbor-vitæ.) Leaves scale-formed, obtuse, closely appressed and very persistent. Cones of 8 or 10 hard, light brown, wedge-shaped scales. Beautiful small trees or generally shrubs (in this country), of a score of named varieties of many colors and forms of plant and foliage.
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.
