Physaria thamnophila
Newberry twinpod, Newberry's twinpod
Zapata bladderpod
several from base, ascending to erect (arising laterally, unbranched), 0.5–1(–2.5) dm.
simple or few from base, decumbent, (straggling and flexuous, usually branched distally), 4–8 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 narrowly elliptic to oblanceolate, 4–12 cm, margins entire, sinuate, or shallowly dentate, (apex acute).
blade linear-oblanceolate to oblanceolate, 1–2 cm, margins entire.
(sessile or proximal shortly petiolate);
blade linear to narrowly elliptic, 3–4 cm, margins entire, sinuate, or remotely dentate, (apex acute).
dense (elongated or not in fruit, 2.5–8.5(–10) cm).
loose, (sometimes greatly elongated).
sepals (greenish yellow), lanceolate, 6–8.5 mm, (saccate and cucullate);
petals spatulate to narrowly oblanceolate, 7–10(–12) mm.
sepals elliptic, 3.5–4 mm, (lateral pair subsaccate, median pair thickened apically, cucullate);
petals broadly obovate, 4–5 mm, (sometimes with short, broad claw).
(divaricate, straight), 5–11(–15) mm, (rigid, fruits not pendent on arching pedicels).
(recurved), 15–20(–25) mm.
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), subglobose or broadly ovoid, slightly compressed, 5–7 mm;
valves (not retaining seeds after dehiscence), glabrous throughout;
ovules per ovary unknown;
style 1.5–2 mm.
slightly flattened, (ovate).

Physaria newberryi
Physaria thamnophila
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 thamnophila is found in sandy areas with shrubs and cactus in sparse shrubland communities of Starr and Zapata counties. It sometimes flowers through September with sufficient moisture.
