Gunneraceae 大叶草科
Gunneraceae is a family of flowering plants. Such a family has been recognized by most taxonomists.
The APG II system, of 2003, also recognizes this family and assigns it to the order Gunnerales in the clade core eudicots. The family then consists of one or two genera, Gunnera and, optionally, Myrothamnus. The latter may also be segregated as a separate family, Myrothamnaceae. This represents a change from the APG system, of 1998, which firmly recognized two separate families, unplaced as to order. The APG III system recognizes the family Gunneraceae and places Myrothamnus in the separate family Myrothamnaceae; both families are placed in the order Gunnerales in the core eudicots.
