Cycads are seed plants with a woody trunk and pinnate leaves, related to ginkgo and conifers. They are gymnosperms with male and female cones, and have specialized pollinators and toxins.
Cycads are gymnosperms distinguished by crowns of large pinnately compound leaves and by cones, which are typically borne at the end of the trunk in the centre of whorled branches. Some cycads have tall unbranched trunks with an armourlike appearance; others have partially buried stems with swollen (tuberous) trunks.

Cycads' Natural Habitat. Cycads predate the continents as we know them, and now remain living in most tropical and subtropical climates. However, due to over-cultivation of forest lands, and open spaces, their habitat loss means they now live in more and more remote areas and have less connected ecosystems.
