Draft FNA: "Symphoricarpos rotundifolius, according to the broadest circumscription (accepted here), is a widespread and variable complex comprising four relatively well distinguished varieties. Indument characters have often been relied upon in the circumscription of taxa. However, the presence and morphology of trichomes varies within all four varieties of S. rotundifolius, and the geographic distributions of indument types are complicated and overlapping. Corolla morphology offers more reliable features. Intermediate specimens not classifiable to variety, even in flower, do exist. A few specimens have been identified, based on morphological intermediacy, as possible hybrids between S. rotundifolius varieties and other sympatric species, including S. albus, S. longifolius, and S. mollis.

Variety vaccinioides is very often labeled Symphoricarpos oreophilus var. utahensis in herbaria and in floristic literature; however, the type of the latter name is referable to S. rotundifolius var. oreophilus."
