The same consistent suite of fertile characters that so well designates the monogeneric Gunneraceae has offered little evidence for direct comparison with other taxa.
For this reason we support placement of Gunneraceae in the order Saxifragales (as recognized by Takhtajan, 1983, 1997).
Alveolarity within Gunneraceae is distinctive in this character because prominent or impressed veins include the penultimate vein order present (e.
