Corollas 13–15 mm; throat moreorless open; teeth of galea bluish or bluish gray, apex rounded, acute, or truncate-acute. 2n = 22.


Phenology: Flowering summer.
Habitat: Clearings, meadows, rocky slopes, open, grassy slopes at edges of mixed woods, roadsides, often on calcareous soils or rocks.
Elevation: 0–600(–2700) m.

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.
