Physaria pruinosa
Newberry twinpod, Newberry's twinpod
frosty bladderpod, Pagosa bladderpod
several from base, ascending to erect (arising laterally, unbranched), 0.5–1(–2.5) dm.
simple or several from base, decumbent or erect, (unbranched), to 2 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).
(petiole sharply differentiated from blade, slender);
blade suborbicular or obovate to rhombic, 4–8 cm, (base abruptly narrowed to petiole), margins entire, sinuate, or shallowly dentate, (abaxial surface densely pubescent, adaxial lightly pubescent).
blade linear-oblanceolate to oblanceolate, 1–2 cm, margins entire.
(proximal petiolate, distal sessile);
blade obovate to rhombic, 0.8–2.3 cm, margins entire or shallowly toothed.
dense (elongated or not in fruit, 2.5–8.5(–10) cm).
dense, (somewhat elongated in fruit).
sepals (greenish yellow), lanceolate, 6–8.5 mm, (saccate and cucullate);
petals spatulate to narrowly oblanceolate, 7–10(–12) mm.
sepals elliptic or oblong, ca. 6 mm, (lateral pair not saccate or subsaccate, cucullate, median pair thickened apically, cucullate);
petals spatulate, ca. 9 mm, (claw expanded at base).
(divaricate, straight), 5–11(–15) mm, (rigid, fruits not pendent on arching pedicels).
(horizontal to ascending, sigmoid or slightly curved), 8–11 mm, (stout).
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).
(sessile or substipitate, often becoming copper-red in age), subglobose or ellipsoid, inflated, 6–9 mm, (firm, glossy);
valves (not retaining seeds after dehiscence), glabrous throughout;
replum as wide as or wider than fruit;
ovules 4–8(–12) per ovary;
style 3.5–7 mm.
slightly flattened, (ovate).
somewhat flattened.
Physaria newberryi
Physaria pruinosa
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.

Of conservation concern.
The one New Mexico population is near the border with Colorado, in Rio Arriba County.
