Cycads are seed plants that shared Earth's forests with the dinosaurs during the Triassic and Crestaceous
periods. About a 100 species exist today, exclusively in the tropics and
subtropics. One species does live in the Florida area. Cycads resemble
palms, but are not closely related. They have seperate male and female
plants that bear seeds in cones.
