原生地・分布（英語）:

説明（英語）: Genus of 14-17 species of evergreen, monoecious, coniferous large shrubs or trees from forest in Australia and New Caledonia. The scale-like adult leaves, 2-4mm (1/16-1/8in) long, have free tips but lie flat along the shoots in whorls of 3; the decurrent parts of the leaves form ridges and furrows on the shoots. Young leaves, 0.8-1.5cm (3/8-1/2in) long, are needle-like and arranged in whorls. The small, ovoid-conical to spherical female cones of most species each have a single whorl of 6 scales, hinged at the bases; male cones are cylindrical or oblong and are borne singly or in groups of 2 or 3. In frost-prone areas, grow tender species in a cool greenhouse or conservatory. In frost-free areas, grow cypress pines as windbreaks or specimen trees. They will tolerate drought, coastal conditions, and saline soils, and thrive in dry, temperate or warm Mediterranean climates.

耐寒性（英語）: Frost hardy to frost tender.
