Cycads, Ginkgoales, Gnetales, persistent survivors …

These survivors of a bygone era belong to three orders: The Ginkgoales with ginkgo biloba, which has survived due to its resilience against air pollution. The cycads, which neither hurricanes nor pests can harm due to their symbiosis with cyanobacteria. And the third, the Gnetales, which include the Ephedra, an ancient medicinal plant, and Welwitschia, which survives from the Namib Desert morning dew with only two leaves thanks to its minimalism.
