description_en: Genus of 18 species of evergreen, coniferous trees from tropical rainforest with a pronounced dry season in New Guinea, Australia, New Hebrides, New Caledonia, Norfolk Island, and South America. The leaves are spirally arranged and usually broadly triangular to needle-like. Male and female cones are green, maturing to brown, and are normally borne on separate trees. The female cones are spherical, ovoid, or ellipsoid, with seeds fused to the bract scale; the male cones are conical or cylindrical. They are all elegant specimen trees and, except for A. araucana, require a warm, temperate climate. In colder areas, grow young plants in a cool conservatory or greenhouse. A. heterophylla may be grown as a houseplant.

hardiness_en: Half hardy to frost tender, except A. araucana, which is fully hardy.
