(ancient Latin name from Greek, Kuparissos). Cypress. Pinaccx. Evergreens, cultivated for their graceful habit and thedark green or glaucous foliage; some are timber trees.
Trees, rarely shrubs, with aromatic evergreen foliage: branchlets quadrangular or nearly so: leaves opposite, small, scale-like, appressed, minutely denticulate-ciliate, on young seedling plants linear-subulate and spreading: flowers monoecious, minute, solitary on short branchlets; staminate ovate or oblong, yellow; pistillate subglobose: cones globular or nearly so, consisting of 3-7 pairs of ligneous, peltate scales, with a mucro or boss on the flattened apex, each bearing many or numerous seeds, but the lower scales usually sterile and smaller; they ripen the second year. - About 12 species in Cent. Amer., north to Calif, and Ariz., and from S. Eu. to S. E Asia. Monogr. by M. T. Masters in Journ, of Linn. Soc. 31:312-51 (1895). By some botanists, the allied genus Chamsecyparis is included.
The cypresses are highly ornamental evergreen trees, greatly varying in habit, hardy only in California and the Gulf states. The hardiest seems to be C. Macnab-iana and C. arizonica, which will stand many degrees of frost in a sheltered position; also C. macrocarpa, C. sempervirens, C. funebris and C. torulosa are of greater hardiness than the others. They stand pruning well, and some species are valuable for hedges, C. macrocarpa being especially extensively planted for this purpose in California. C. arizonica yields excellent timber. The cypresses seem not to be very particular in regard to soil and situation, but prefer a deep, sandy-loamy soil. For propagation, see Chamaqecyparis. The young plants should be removed several times in the nursery to secure a firm root-ball; otherwise they will not bear transplanting well.
