few to several from base, erect or outer decumbent, 0.5–2.5 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 suborbicular to elliptic or ovate or deltate, 0.5–2(–6.5) cm, margins entire or shallowly dentate.
blade linear-oblanceolate to oblanceolate, 1–2 cm, margins entire.
(proximal shortly petiolate, distal usually sessile);
blade narrowly elliptic or obovate, (0.5–)1–2.5(–4) cm, margins entire.
dense (elongated or not in fruit, 2.5–8.5(–10) cm).
compact, (± subumbellate to densely corymbiform, elongated or not).
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 shortly stipitate, less than 1 mm), subglobose to broadly ellipsoid, inflated or slightly compressed (terete or subterete), (4–)5–8(–9) mm;
valves (not retaining seeds after dehiscence), glabrous;
replum as wide as or wider than fruit;

slightly flattened, (ovate).
flattened.
Physaria newberryi
Physaria ovalifolia
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.
