Order Cycadales

Order Cycadales

Cycads are primitive seed plants that were once growing in profusion all over the world. Most species are now extinct but a few of their descendants remain. They probably evolved from ancient "seed-ferns" that flourished 500 million years ago. Cycads grow in sub-tropical regions including Australia. As in the Ginkgos, male and female plants are separate and the male pollen produces a swimming sperm cell. [CH] {EN}
