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.

Collinsia multicolor is known from the Santa Cruz Mountains. The flowers of C. multicolor are similar to those of C. heterophylla, including markings at the base of the banner; C. multicolor lacks the curved basal spurs at the bases of the adaxial filaments, and its banner lobes and wings are notched. In C. multicolor, the adaxial side of the corolla tube is rounded and slightly gibbous, unlike the tube of C. heterophylla, which is saccate basally.
