The genus Balsamorhiza (Asteraceae) is comprised of approximately 12 species and can be found throughout western North America, with four species occurring in Montana. There has been speculation of interspecific natural hybridization within this genus for at least 70 years, however research in the area has been insufficient and failed to confirm this. In northwest Montana, B. sagittata and B. incana are commonly found and their ranges overlap in several counties. Individuals showing intermediate traits between these two species were identified in overlapping ranges and documented as potential hybrids. Utilizing herbarium specimens, a comparative morphological analysis of B. sagittata, B. incana, and the putative hybrids was conducted, and a molecular circumscription of this group is currently in progress, utilizing the ITS region of the nuclear ribosomal DNA. Resulting morphological data show that phenotypic characteristics in the putative hybrids are clearly intermediate, yet distinct from either of the parents, indicating hybridization.
