simple or few to several from base, erect or decumbent, (rarely branched, usually leafy), to 4 dm.
(ascending to erect, petiole slender);
blade oblanceolate to obovate, 3–8 cm, (base tapering to petiole), margins incised or dentate with broad teeth, (apex acute to obtuse).
blade lyrate-pinnatifid, 1–7 cm, margins entire or shallowly dentate.
blade linear-oblanceolate to oblanceolate, 1–2 cm, margins entire.
(sessile or shortly petiolate);
blade narrowly obovate to elliptic, 0.5–6 cm, margins entire, repand, or shallowly dentate.
dense (elongated or not in fruit, 2.5–8.5(–10) cm).
dense, (elongated in fruit, often subtended by distal cauline leaves).
sepals (greenish yellow), lanceolate, 6–8.5 mm, (saccate and cucullate);
petals spatulate to narrowly oblanceolate, 7–10(–12) mm.

replum linear to linear-lanceolate, as wide as or wider than fruit, apex acute;
ovules 4–8 per ovary;
style 2–9 mm, (usually not exceeding sinus).
(sessile or substipitate), globose or broadly obovate, not inflated, 4–6 mm, (smooth);

Physaria newberryi
Physaria densiflora
Subspecies 2 (2 in the flora).
Physaria newberryi, with its unusual fruits, can be confused with 15. P. chambersii. In P. chambersii, the sides of the fruit are flat, the style always exceeds the top, or shoulders, of the fruit, and shoulders form an angle that does not curve in toward the style. In P. newberryi, the sides of the fruit are concave, the styles are shorter than shoulders of the silicle (except in subsp. yesicola), and shoulders of the silicle form a curved, inward arching crown on the fruit.

Alyssum densiflorum (A. Gray) Kuntze (1891), not Desfontaines (1808) is an illegitimate name, sometimes found in synonymy with Physaria densiflora.
