Notes: FNA: "The taxonomic and nomenclatural treatment of this taxon has been variable. Material from northwest North America and northeast Asia is not taxonomically distinguishable, a conclusion also reached by C. L. Li, H. Ikeda, and H. Ohba (1994). The name Sanguisorba sitchensis has been customarily applied to North American material, but the oldest name available for a taxon bridging the Bering Strait is S. stipulata. An additional taxonomic question is the relationship of this taxon to eastern North American S. canadensis. While similar and undoubtedly closely related, the taxa differ in several morphologic characters, are strongly allopatric in distribution, and are here regarded as sibling species."
