The Gnetophytes are a group of seed plants with three genera. Their evolutionary relationships are unclear, but it is now clear that they are related to each other.[1]
The three genera are:
By looking at the structure of these organisms (morphology) and the DNA (molecular taxonomy), scientists have found that Gnetum and Welwitschia are more closely related to each other than to Ephedra.[2][3][4][5]
