The Gnetophyta are a division of the plant kingdom, included among the gymnosperms. Living representatives are found in 3 families in the Class Gnetopsida, Order Gnetales. These three families are Gnetacaea (Gneturns), Welwitschiaceae (Welwitschia), and the Ephedraceae (Mormon-teas). Each family is represented by just one genus. Subcategories for the Gnetophyta are established at the family level for the Ephedraceae and the genus level for the other representatives.
