Gunneraceae

Taxonomy

Gunnera is the only genus in the family Gunneraceae. The APG II system of 2003 accepted this family and assigned it to the order Gunnerales in the clade core eudicots. The family then consisted of one or two genera, Gunnera and, optionally, Myrothamnus, the latter optionally segregated as a separate family, Myrothamnaceae. This represents a change from the APG system of 1998, which accepted two separate families, unplaced as to order. The APG III system and APG IV system accept the family Gunneraceae, and places Myrothamnus in Myrothamnaceae; both families are placed in the order Gunnerales in the core eudicots.
