Fruits usually ascending to suberect, rarely divaricate-ascending, narrowly linear, straight or curved inwards, not torulose, (3–) 5–13 cm × 2.2–5 mm, terete when immature, becoming strongly latiseptate, not striped; valves with obscure midvein, pubescent outside, trichomes 2–5-rayed, glabrous inside; ovules 42–68 per ovary; style cylindrical or flattened, stout, 0.5–2.5 mm, sparsely pubescent; stigma 2-lobed, lobes as long as wide. Seeds broadly ovate to suborbicular, (1.5–) 2–4 × 1.5–3 mm; wing continuous. 2n = 36.

Discussion
Erysimum concinnum is a coastal species known from Curry County in Oregon, and from Del Norte, Humboldt, Marin, Mendocino, and Sonoma counties in California. Both G. B. Rossbach (1958) and R. C. Rollins (1993) treated it as a distinct species, but R. A. Price (1993) reduced it (invalidly) to a subspecies of E. menziesii.
