Abstract: Welcome to the intriguing world of Cycads, survivors from before the dinosaurs! The Cycad Pages provide Web access to a botanical database developed from The World List of Cycads, with a page for every known cycad. The cycads are a small group of plants with many unique features, an ancient origin and a very long history. Cycads are known to have lived in the Permian era, over 200 million years ago - even before the dinosaurs roamed the earth. Although once abundant across the globe, the cycads are now greatly reduced in both numbers and distribution. There are now about 250 species in 11 genera, compared to possibly 300,000 species of flowering plants, the group that now dominates the world vegetation. All cycads are tropical or subtropical and each genus has a restricted geographical range. [Information of the supplier, modified]
