Cycad

Cycads /ˈsaɪkædz/ are seed plants with a very long fossil history that were formerly more abundant and more diverse than they are today. They typically have a stout and woody (ligneous) trunk with a crown of large, hard and stiff, evergreen leaves. They usually have pinnate leaves. The species are dioecious, therefore the individual plants of a species are either male or female. Cycads vary in size from having trunks only a few centimeters to several meters tall. They typically grow very slowly and live very long, with some specimens known to be as much as 1,000 years old. Because of their superficial resemblance, they are sometimes mistaken for palms or ferns, but they are not closely related to either group.

Cycads became more and more prominent as you went south of Dodge City provided there was water available. Cycadia was named after the plant since a large number of them grew around its year round spring.
