Discussion

Collinsia grandiflora occurs mostly in the coastal ranges. The distinction between C. grandiflora and C. parviflora is usually clear in California where corolla lobe shape and size are mostly well correlated. The distinction is much less clear in British Columbia, Oregon, and Washington.

An alternative to the treatment here would be to follow F. R. Ganders and G. R. Krause (1986), who suggested that Collinsia grandiflora and C. parviflora be treated as one species with two intergrading varieties.
