Discussion | A report of Collinsia wrightii (as C. torreyi var. wrightii) from western Nevada (J. T. Kartesz 1987) has not been verified by the author. Collinsia wrightii is often confused with C. parviflora and less frequently with C. torreyi. The corolla of C. wrightii is purplish as in C. torreyi and not the bright blue of C. parviflora. Collinsia wrightii and C. parviflora differ most evidently in plant stature and corolla size; C. wrightii is generally more diminutive. The large-flowered form of Collinsia wrightii, corolla (6–)8–9 mm, has been treated as C. torreyi var. brevicarinata and occurs only near Kings Canyon and Sequoia national parks. The flowers are similar in size to those of C. torreyi as treated here but differ in corolla shape (wings surpassing tip of keel by 1.5–2 mm) and leaf shape and length. The seeds of the large-flowered form are compressed; those of the small-flowered form are not. A phylogenetic study (B. G. Baldwin et al. 2011) showed that Collinsia wrightii and C. torreyi belong to divergent lineages and supports the recognition of these taxa as distinct species based on differences in the lengths of the wings relative to the tips of the keels.
