Discussion

Collinsia antonina is geographically narrowly endemic, known only from Monterey County. It occurs on scree derived from whitish siliceous shale of the Monterey Formation at the edge of woodlands near the shade of Quercus john-tuckeri. It is morphologically similar to C. parryi, which lacks the coarse white hairs on the inner face of the sepals. DNA studies (B. G. Baldwin et al. 2011) show a more distant relationship between C. antonina and C. parryi than suspected from morphology alone.

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.
