Var. _flagelliformis_, Jacq. (Weeping Arbor-vitæ), has very slender, elongated, weeping branches, curving gracefully to the ground. It is a beautiful variety, often cultivated (a single stem is shown in the figure). GENUS =104. CHAMÆCÝPARIS.= (THE CYPRESSES.) Strong-scented, evergreen trees with very small, scale-like or somewhat awl-shaped, closely appressed (except in some cultivated varieties), overlapping leaves and 2-ranked branchlets, almost as in Thuya. Cones globular, with peltate, valvate scales, firmly closed till ripe; the scales thick and pointed at the center. * Native trees; leaves light glaucous-green. 1. * Cultivated trees from Western America; leaves dark green. (=A.=) =A.= No tubercle on the backs of the leaves. 2. =A.= Usually a tubercle on the back 3. * Cultivated small trees and shrubs from Japan (called Retinospora) 4. [Illustration: C. sphæroídea.] 1. =Chamæcýparis sphæroídea=, Spach. (WHITE CEDAR.) Leaves very small, triangular, awl-shaped, regularly and closely appressed in 4 rows, of a light glaucous-green color, often with a small gland on the back. Cones very small, 1/3 in. in diameter, of about 6 scales, clustered. Tree 30 to 90 ft. high, wild in low grounds throughout; abundant in Middle States. With reddish-white wood and slender, spreading and drooping sprays; bark fibrous, shreddy; sometimes cultivated. [Illustration: C. Nutkænsis.] 2. =Chamæcýparis Nutkænsis=, Lambert. (NOOTKA SOUND CYPRESS.) Leaves only 1/8 in. long, sharp-pointed, and closely appressed, of a very dark, rich green color; very slightly glaucous, without tubercles on the back. Cones small, globular, solitary, with a fine, whitish bloom; scales 4, rough and terminating in a sharp straight point. Tree 100 ft. high in Alaska, and would make a fine cultivated tree for this region if it could stand our hot, dry summers. [Illustration: C. Lawsoniàna.] 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. [Illustration: 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.
