Discussion

The name Rhinanthus crista-galli has been misapplied to R. minor by numerous European and American authors. All reports of R. crista-galli from eastern North America appear to be based on subsp. minor. Reports of subsp. minor from North Dakota and Rhode Island are probably erroneous; confirming specimens could not be found. Populations of subsp. minor usually are associated with some type of anthropogenic disturbance.
