Discussion | Varieties 5 (1 in the flora). The Poterium sanguisorba complex has been treated in various and complex ways in Europe; a consensus has not emerged as to the number of species or infraspecific taxa to be recognized.

Variation in the number of genera in subfam. Rosoideae is due to differences in generic delimitation between D. Potter et al. (2007) and the authors of some Potentilleae genera. Cyanogenic glycosides and sorbitol are absent in the subfamily. Tribes 6, genera 28–35, species ca. 1600 (6 tribes, 26 genera, 302 species, including 1 hybrid, in the flora) (Discussion copyrighted by Flora of North America; reprinted with permission.) |
