Rubus multiformis is an uncommon North American species of flowering plant in the rose family. It is found in eastern Canada (New Brunswick, Nova Scotia) and the northeastern and north-central United States (Maine, Vermont, New York, Michigan, Wisconsin).[http://bonap.net/MapGallery/County/Rubus%20multiformis.png Biota of North America Program 2014 county distribution map][https://www.biodiversitylibrary.org/page/563061#page/221/mode/1up Blanchard, William Henry. 1906. Rhodora 8(93): 179-180]

The genetics of Rubus is extremely complex, so that it is difficult to decide on which groups should be recognized as species. There are many rare species with limited ranges such as this. Further study is suggested to clarify the taxonomy.[http://www.efloras.org/florataxon.aspx?flora_id=1&taxon_id=128837 Flora of North America, Rubus Linnaeus, 1754. Bramble ] Some studies have suggested that R. multiformis may have originated as a hybrid between R. setosus and R. flagellaris.
