Physaria newberryi
Physaria pallida
Newberry twinpod, Newberry's twinpod
white bladderpod
several from base, ascending to erect (arising laterally, unbranched), 0.5–1(–2.5) dm.
few to several from base, erect, (from basal leaf cluster, branched distally, flowering branches slender, subtended by bracts), 3–6 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 oblanceolate or broadly obovate, to 10 cm, margins usually sinuate-dentate or entire, sometimes lobed.
blade linear-oblanceolate to oblanceolate, 1–2 cm, margins entire.
(proximal shortly petiolate, distal sessile);
blade oblanceolate to narrowly oblong, similar to basal, (distal with base slightly cuneate).
dense (elongated or not in fruit, 2.5–8.5(–10) cm).
paniculate, (rachises and pedicels more densely pubescent than proximal leaves).
sepals (greenish yellow), lanceolate, 6–8.5 mm, (saccate and cucullate);
petals spatulate to narrowly oblanceolate, 7–10(–12) mm.
sepals elliptic, 3–7 mm, (median pair slightly thickened apically, cucullate);
petals (white), broadly ovate, to 12 mm, (narrowing gradually to short claw).
(divaricate, straight), 5–11(–15) mm, (rigid, fruits not pendent on arching pedicels).
(widely divaricate-ascending and straight, or slightly recurved), 10–15 mm, (slender, pubescent).
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).
(widely spreading to nearly pendent in age, shortly stipitate), globose or subglobose, not or slightly inflated, 3–10 mm;
valves (not retaining seeds after dehiscence), glabrous;
replum as wide as or wider than fruit;
ovules 8–12 per ovary;
style ca. 2 mm, (slender, fragile).
slightly flattened, (ovate).

Physaria newberryi
Physaria pallida
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.
Physaria pallida is known from the Weches Formation in San Augustine County.
