Annuals; hispid basally, glabrous or subglabrate distally. Stems erect, usually branched distally, 2.5–12 dm, hispid. Basal leaves weakly rosulate; petiole 0.3–3 cm; blade linear-oblanceolate to linear-oblong, 0.7–7 cm × 2–18 mm, margins coarsely dentate or pinnately lobed. Cauline leaves (median) sessile; blade linear-lanceolate, 5–16 cm × 5–40 mm, (smaller distally, base amplexicaul to sagittate), margins dentate or (distalmost) entire. Racemes (densely flowered), without a terminal cluster of sterile flowers. Fruiting pedicels reflexed, 2–8 mm, glabrous or hispid. Flowers: sepals erect (purple or yellow to creamy white), lanceolate, 3–8 × 1–1.8 mm (equal); petals purple or yellowish (often with darker purple veins), 5–15 mm, blade 2–6 × 1–1.5 mm, not crisped, claw narrowly oblanceolate or oblong, 3–9 × 1–1.5 mm; filaments tetradynamous, median pairs 3–6 mm, lateral pair 2–5 mm; anthers oblong, equal, 1–3 mm. Fruits reflexed (often straight, rarely curved), latiseptate or 4-angled, 4.5–10 cm × 1–1.5 mm; valves each with prominent midvein; ovules 56–82 per ovary; style 0.5–3.5mm; stigma slightly 2-lobed. Seeds 1.2–2 × 0.9–1.4 mm. 2n = 28.
Phenology: Flowering Mar–May.
Habitat: Coastal scrub, chaparral, rocky areas
Elevation: 0-1400 m

Discussion
Caulanthus heterophyllus is a common species distributed from Santa Barbara County southward into northwestern Baja California, Mexico.
