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; (delicate, short-lived); caudex simple, (sometimes elongated, covered with persistent leaf bases); usually sparsely pubescent, trichomes 7–12-rayed, rays furcate near base. | ||||
Stems | several from base, ascending to erect (arising laterally, unbranched), 0.5–1(–2.5) dm. |
simple from base, erect to decumbent, (unbranched, mostly filiform, slender), 1–1.5 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). |
(erect, petiole slender); blades broadly ovate to elliptic, 0.5–1 cm, (base abruptly narrowing to petiole), margins entire. |
||||
Cauline leaves | blade linear-oblanceolate to oblanceolate, 1–2 cm, margins entire. |
(remote, distally shortly petiolate); blade ± spatulate, (base cuneate), margins entire. |
||||
Racemes | dense (elongated or not in fruit, 2.5–8.5(–10) cm). |
lax, (elongated, few-flowered). |
||||
Flowers | sepals (greenish yellow), lanceolate, 6–8.5 mm, (saccate and cucullate); petals spatulate to narrowly oblanceolate, 7–10(–12) mm. |
sepals (erect), oblong, 3.5–4 mm, (lateral pair not saccate); petals (often fading to light purple apically), spatulate to nearly lingulate, 6–7 mm. |
||||
Fruiting pedicels | (divaricate, straight), 5–11(–15) mm, (rigid, fruits not pendent on arching pedicels). |
(recurved to widely spreading, filiform, slender), 5–10 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). |
(pendent), globose or subglobose, compressed, 3–4 mm; valves ± densely pubescent; ovules 6–10 per ovary; style ca. 1.5 mm. |
||||
Seeds | slightly flattened, (ovate). |

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.
