Rubus probabilis is an uncommon North American species of bramble.
The genetics of Rubus is extremely complex, making it difficult to decide which groups should be recognized as species. As there are many rare species with limited ranges, further study is suggested to clarify the taxonomy.Flora of North America, Rubus Linnaeus, 1754. Bramble
