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.
