In Iceland and southern Greenland, a few populations have been found that may be hybrids between F. rubra and either F. frederikseniae or F. vivipara. The purported hybrids have been named F. x villosa-vivipara. All these species grow on cliffs and on rocky or sandy soils in alpine tundra. It was first described in 1985.

It is found in eastern and central Canada (from Ontario to Nova Scotia) and the northeastern United States (Maine, New York, Pennsylvania). The epithet biformispinus means "with spines of two shapes," referring to the two distinct sizes of prickles on the stems. 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
