| | Cycad - Wikipedia, the free encyclopedia |
 | | Zamiaceae is more diverse, with a fossil record extending from the Middle Triassic to the Eocene (54 – 200 mya) in North and South America, Europe, Australia, and Antarctica, implying that the family was present before the break-up of Pangea. |
 | | African cycads are rare and are thought to be naturally decreasing due to small population sizes, and there is controversy over whether to let natural extinction processes act on these cycads. |
 | | All cycads are in the CITES appendix appearing under the heading Plant Kingdom and under three family names, Cycadaceae, Stangeriaceae and Zamiaceae. |
