Sciadopitys (Greek, skias, skiados, umbrella, and pitys, spruce, alluding to the position of the leaves). Pinaceae. Umbrella Pine. Ornamental tree grown for its handsome foliage and regular pyramidal habit. Evergreen resinous tree: lvs. of two kinds; small and scale-like lvs. scattered on the shoot, but crowded at its end and bearing in their axils a whorl of 20-30 long linear flat lvs. furrowed on each side, more deeply beneath; these lvs. really consist each of 2 connate lvs. borne on undeveloped spurs like those of Pinus; they have been sometimes called cladodes, but are not true cladodes: fls. monoecious; the staminate oval, consisting of spirally disposed 2-celled anthers and appearing in dense clusters at the ends of the shoots; the pistillate are solitary at the ends of the shoots and consist of numerous spirally arranged scales subtended by a small bract and bearing 7-9 ovules: cone oblong-ovate, woody, the bracts connate, with the broadly orbicular thick scales spreading at the margin; seeds oval, compressed, with narrow wing, emarginate at the apex.— One species in Japan, with very strong and straight-grained, nearly white wood. The umbrella pine is a very handsome tree of narrow pyramidal habit, with linear rather large, needle-like dark green and lustrous leaves in whorls and oval cones 3 to 4 inches long. It is hardy as far north as Portland, Maine, and is of rather slow growth. It thrives well in a moderately and constantly moist, loamy, and also in clayey soil; in dry soil or in soil which periodically becomes dry, it grows poorly. Propagation is by seeds and layers, and sparingly by cuttings of half-ripened wood in summer; but seedlings are to be preferred, as they grow more symmetrically and more vigorously.CH
