Gunnera

Gunnera is the sole genus of herbaceous flowering plants in the family Gunneraceae, which contains 63 species. Some species in this genus, namely those in the subgenus Panke, have extremely large leaves. Species in the genus are variously native to Latin America, Australia, New Zealand, Papuasia, Hawaii, insular Southeast Asia, eastern Africa, and Madagascar. The stalks of some species are edible. 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. The genus Gunnera was named after the Norwegian botanist Johann Ernst Gunnerus.
