Genus of about 15 species of cycads found mainly on dry, stony slopes and in semi-desert and dry, open woodland from Madagascar to S. and S.E. Asia, Australia, and the Pacific islands. The Sago Palm (Cycads) are distinctly Palm-like in appearance but they are not closely related to the true palms. Only one species is grown as a house plant - Cycas reviluta. It is an extremely slow-growing plant, putting out just one growth (1-60 leaves) per year. It is very difficult to grow Cycas in ordinary room conditions.
