Mitchella repens — partridge-berry

Facts

Partridge-berry is common in dry-mesic to wet-mesic forest floors where it scrambles along the ground. The red, edible but insipid fruits are unusual in that they are formed from two 4-merous flowers by the fusion of their two ovaries, thus each berry-like drupe contains eight seeds.
