Poterium sanguisorba L. var. polygamum (Waldst. & Kit.) Vis.[FNA9, HC2]

burnet bloodwort, fodder burnet, small burnet

Publication: Fl. Dalmat. 3: 255. 1852.

Origin: Introduced from Eurasia and North Africa

selected vouchers: WTU

Notes: Draft FNA9: "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 infraspecies taxa to be recognized.

All North American material of Poterium belongs to P. sanguisorba var. polygamum. Reports of Sanguisorba minor or Poterium sanguisorba are using that in a broad sense, not distinguishing the varieties or subspecies variously recognized, and do not imply the occurrence of the typic infrataxon in North America. It is possible that the typical variety (or other infrataxa, as defined in the European literature) is present in North America."
