Gnetopsida - SpringerLink
Abstract. The extant taxa Ephedra, Gnetum and Welwitschia were earlier placed in a single order, Gnetales, and a single family, Gnetaceae. These three taxa (considered to be the highest evolved among the gymnosperms) lack fossil record except for the remains of pollen of Ephedra from the Eocene (54 my B.P.), and pollen-like remains of Ephedra ...
