Discussion

Of conservation concern.

Sanguisorba menziesii sometimes has been treated as a hybrid between S. officinalis and S. stipulata. Some of its characteristics do suggest intermediacy; it is possible that it arose via hybridization, but it seems best to regard it as a species, because it forms populations separate from its possible parents and is fully fertile (P. S. Holloway and G. E. M. Matheke 2003).
