'Giant rhubarb' Gunnera manicata, from here.

Belongs within: Eudicotyledoneae.
Contains: Balanophorales, Dilleniaceae, Saxifragales, Rosidae, Santalanae, Caryophyllales, Asteridae.

The Gunneridae is a major clade of flowering plants, corresponding to the eudicotyledons minus the basal 'ranunculids' of some classifications. Cantino et al. (2007) defined the Gunneridae as the smallest clade containing Gunnera perpensa and Helianthus annuus. The clade is mostly supported by molecular analyses, but another synapomorphy may be the presence of ellagic acid. The major subclade within the Gunneridae, the Pentapetalae, is characterised by the ancestral possession of pentamerous flowers (altered in many subsidiary lineages) (Cantino et al. 2007).
