Cycas revoluta (Sago Cycad), is a cycad native to southern Japan. Though often known by the common name of King Sago Palm, or just Sago Palm, it is not a palm at all. Cycas refers to the genus, the genus refers to a particular group of similar plants in the Cycad family and revoluta further describes the exact species of the group Cycas. The latter was given to this species because of the revolute (to curl back) nature of the leaflets; the edges roll under the leaflet.
