The Cycadaceae and Zamiaceae are families of the Cycadophyta with a primarily tropical/subtropical distribution.
The Cycadaceae are composed of only a single genus, Cycas,with about 20 species, whereas the Zamiaceae are composed of around 8 genera and approximately 110 species.
The Cycadaceae are thought to be the oldest extant lineage of cycads and apparently are the sister group to all other cycads.
