They grow best in somewhat moist but well-drained, sandy loam and in a partly shaded position, sheltered against dry winds. C. Lawsoniana and C. obtusa like more dry, the others more moist situations, and C. thyoides grows well even in swamps. Propagated by seeds sown in spring; increased also by cuttings from mature wood in fall, inserted in a sandy soil and kept in a coolframe or greenhouse during the winter; if in early spring gentle bottom heat can be given, it will hasten the development of roots considerably. All the so-called retinosporas and the dwarfer forms, and most of the varieties of C. Lawsoniana, are readily increased in this way, while the other forms of C. noolkatensis, C. obtusa and C. thyoides do not grow well from cuttings; therefore for most varieties veneergrafting on seedling stock during the winter in greenhouse is preferred, but dwarf forms always should be grown from cuttings, as they often lose their dwarf habit if grafted. The so-called retinosporas of the gardens, with linear, spreading leaves, are juvenile forms, which have retained the foliage of the seedling state. There are similar forms in Thuja. For their distinguishing characters, see Retinospora. For the numerous gardens forms, see Beissner, Handb. der Nadelholzk., 2d ed., pp. 528-574, quoted below as Beissner. | They grow best in somewhat moist but well-drained, sandy loam and in a partly shaded position, sheltered against dry winds.

Chamaecyparis (chamai, dwarf, and kuparissos, cypress; referring to its affinity). Pinaceae. Trees or shrubs grown for their handsome evergreen foliage; also valuable timber trees; Retinosporas, in part. Evergreen, with opposite scale-like lvs. in 4 rows, densely clothing the compressed branchlets: fls. monoecious, small; pistillate inconspicuous, globose; staminate yellow or red, oblong, often conspicuous by their abundance: cones small, globular, with 6-11 bracts, each bearing 2, or rarely 5, winged seeds, ripening the first season. Closely allied to Cupressus, which differs in its larger cones maturing the second year, the bracts containing 4 or more seeds, and in its quadrangular branches and minutely denticulate lvs.—Six species in N. Amer. and E. Asia, all very valuable timber trees in their native countries. Highly ornamental evergreen trees of pyramidal habit, of which only C. thyoides is fully hardy N., while the Japanese species are hardy in sheltered positions north to New England, and C. Lawsoniana only from Mass. south; the horticultural varieties are often shrubby. They grow best in somewhat moist but well-drained, sandy loam and in a partly shaded position, sheltered against dry winds. C. Lawsoniana and C. obtusa like more dry, the others more moist situations, and C. thyoides grows well even in swamps. Propagated by seeds sown in spring; increased also by cuttings from mature wood in fall, inserted in a sandy soil and kept in a coolframe or greenhouse during the winter; if in early spring gentle bottom heat can be given, it will hasten the development of roots considerably. All the so-called retinosporas and the dwarfer forms, and most of the varieties of C. Lawsoniana, are readily increased in this way, while the other forms of C. noolkatensis, C. obtusa and C. thyoides do not grow well from cuttings; therefore for most varieties veneergrafting on seedling stock during the winter in greenhouse is preferred, but dwarf forms always should be grown from cuttings, as they often lose their dwarf habit if grafted. The so-called retinosporas of the gardens, with linear, spreading leaves, are juvenile forms, which have retained the foliage of the seedling state. There are similar forms in Thuja. For their distinguishing characters, see Retinospora. For the numerous gardens forms, see Beissner, Handb. der Nadelholzk., 2d ed., pp. 528-574, quoted below as Beissner. C. formosensis, Matsum. (Cupressus formosensis, Henry). Allied to C. pisifera. Tree, to nearly 200 ft. and 20 ft. diam.: branchlets dull green on both surfaces or slightly bloomy below: lvs. acute, ovate: cones ovoid, 1/3in. across, with 10 or 11 scales. Formosa. G.C.
