Habit | Perennials; caudex simple or branched, (branches often covered with persistent leaf bases, cespitose); densely (silvery) pubescent, trichomes rays fused at least 1/2 their length. | Perennials; caudex simple; densely pubescent, trichomes (often wavy, closely appressed to blade surfaces), 4–5-rayed, rays furcate or bifurcate, slightly fused near base, (tuberculate throughout). | ||||
Stems | several from base, ascending to erect (arising laterally, unbranched), 0.5–1(–2.5) dm. |
simple from base, loosely spreading, usually decumbent, (well exserted from basal leaves, often reddish purple), 0.8–2.4 dm. |
||||
Basal leaves | (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 (erect), spatulate to nearly rhombic, 2.5–5(–9) cm, (base gradually narrowed to petiole), margins entire, (flat). |
||||
Cauline leaves | blade linear-oblanceolate to oblanceolate, 1–2 cm, margins entire. |
blade spatulate, similar to basal, margins entire. |
||||
Racemes | dense (elongated or not in fruit, 2.5–8.5(–10) cm). |
loose, (elongated, exceeding basal leaves). |
||||
Flowers | sepals (greenish yellow), lanceolate, 6–8.5 mm, (saccate and cucullate); petals spatulate to narrowly oblanceolate, 7–10(–12) mm. |
sepals (pale yellow), lingulate to spatulate, 3.5–4 mm; petals narrowly oblanceolate, 4–6 mm. |
||||
Fruiting pedicels | (divaricate, straight), 5–11(–15) mm, (rigid, fruits not pendent on arching pedicels). |
(ascending, curved or sigmoid), 4–7 mm. |
||||
Fruits | didymous, sides curved and angular, highly inflated, 6–16 × 8–12 mm, (papery, apical sinus broad and concave); valves (retaining seeds after dehiscence, distinctly 2-keeled on side away from replum), pubescent, trichomes appressed; 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). |
ellipsoid, not inflated (strongly latiseptate, more so at apex), (3–)5–9 mm; valves pubescent, trichomes closely appressed to surface; ovules 4–8 per ovary; style 2.5–4.5 mm (never more than 1/2 fruit length). |
||||
Seeds | slightly flattened, (ovate). |
plump. |

Discussion | 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.
