Annuals 5–25 cm. Stems erect to ascending. Leaf blades elliptic to ovate, length usually 2–5 times width, margins entire or serrate. Inflorescences densely glandular; nodes (1–)3–6-flowered; flowers not crowded; distalmost bracts linear, 0–2 mm. Pedicels ascending to spreading, sometimes reflexed, pendent and/or sigmoid in fruit, usually longer than calyx, visible. Flowers: calyx lobes lanceolate to ovate, equal to capsule, ape× subacute to rounded; corolla blue-violet to purple, banner white, cream, or pale lilac, 6–9 mm, sparsely glandular; banner length 0.7–0.8(–0.9) times wings, lobe base with folds bulging 0.5 mm away from throat opening at base of each lobe, wings equal to keel; stamens: abaxial filaments glabrous, adaxials glabrous or hairy at base, basal spur 0. Seeds 2, ovate to oblong, often curled toward attachment side, 2–2.5 mm, margins thickened, inrolled.
Phenology: Flowering Jun–Aug.
Habitat: Mixed oak-conifer forests, openings near montane chaparral.
Elevation: 1000–2500 m.
Discussion
Collinsia latifolia occurs on volcanic and metamorphic substrates in northern California and southern Oregon in the Klamath and Cascade ranges, and in the North Coast Ranges of California. Its flowers are nearly identical to those of C. torreyi, which differs in leaf shape: linear in C. torreyi and elliptic to ovate in C. latifolia.
