Cycas is genus of species of palmlike cycads in the family Cycadaceae native to tropical and subtropical areas of the Old World. The leaves of sago palm (Cycas revoluta) are widely used as ceremonial “palms” and in floriculture. The pithy stems of this and other species are a source of sago, a food starch. Several species, among them the Australian nut palm (C. media) and queen sago (C. circinalis), a fern palm of the Malaysian area, bear edible seeds. A number are cultivated as houseplants and in conservatories and can be grown outdoors as ornamentals in warm climates.
