Infestations of Aulacaspis yasumatsui, otherwise known as cycad aulacaspis scale, have been known to affect D.
In Florida, the larva (caterpillar) feeds on a native cycad, Zamia pumila, called Coontie, as well as introduced ornamental cycads.
The toxin can however be removed by careful leaching, and the roots and half-buried stems of this cycad were used by Native American people (notably the Tequesta and Mayaimi Indians, the Seminole Indians and the Maroons) to produce this starch.
Ginkgo trees and cycads were plentiful during this period, as were reptiles such as Lystrosaurus.
The gardens also has a large collection of native and introduced tropical plants including cycads, palms, Adansonia, gingers and heliconias.

Microcycas is a genus of cycads in the family Zamiaceae containing only one species, Microcycas calocoma, endemic to a small area in western Cuba in Pinar del Río Province.
It was home to the giant Wood's Cycad (Encephalartos woodii) which has been extinct in the wild since the early 1900s.
Was identified, confirmed that this is a rare new species of Cycas, known as "Panzhihua Cycad" and given the botanical name Cycas panzhihuaensis.
Besides the plant remains that might have been expected, such as cycads and conifers, discoveries published in 2005 revealed an unexpectedly wide range of monocotyledons, including palms and grasses (Poaceae), including ancestors of rice and bamboo, which has given rise to speculation that herbivorous dinosaurs and grasses co-evolved.
