Discussion

Collinsia childii occurs principally on shaded, rocky soil. It is most common in the Sierra Nevada and Transverse ranges in the interior of southern California. There are also isolated populations in the South Coast Ranges.

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.
