distribution_en:

description_en: Genus of 250 or more species of dioecious, evergreen shrubs and trees occurring in dry and moist sites throughout tropical regions of Africa, India, Asia, Australasia, and the Pacific islands. The sparsely branched stems of mature plants are often supported by stilt roots. Screw pines are grown for their attractive foliage: the linear, light to dark green leaves are tough and usually spiny-toothed, and borne in 3 spiralling ranks forming terminal rosettes. The small and petalless male and female flowers are produced on separate plants, males in slender, often branched spikes, and females in short, dense, cone-like heads, which develop into small, fruits resembling pineapples when fertilized. Where temperatures fall below 13°C (55°F), grow young plants in a warm greenhouse or as houseplants. In warmer regions, use as specimen plants.
