Interpretive Summary:

Technical Abstract: This chapter begins with a brief taxonomic overview of the genus Rubus in Minnesota. Rubus is the most diverse shrub genus in Minnesota, including 33 recognized species, along with two named, interspecific hybrids. These 35 taxa are assigned to five subgenera, with the most speciose (subgenus Rubus) represented by six different sections. The introductory overview also includes advice on how to identify and voucher Rubus populations. A dichotomous key follows. The remainder of the chapter consists of individual descriptions for each species. These descriptions focus on morphological and phenological characters, earlier taxonomic treatments, and natural history observations pertinent to Minnesota field conditions.
