Physaria newberryi
Physaria gracilis
Newberry twinpod, Newberry's twinpod
spreading bladderpod
several from base, ascending to erect (arising laterally, unbranched), 0.5–1(–2.5) dm.
simple to several from base, erect, often outer decumbent, (unbranched or branched distally), 1–7 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 to elliptic, 1.5–8(–11.5) cm, margins lyrate-pinnatifid to dentate or repand, (abaxial surface densely pubescent, adaxial sparsely pubescent).
blade linear-oblanceolate to oblanceolate, 1–2 cm, margins entire.
(proximal petiolate, distal sessile);
blade oblanceolate to oblong, 1–7 cm, margins dentate to repand.
dense (elongated or not in fruit, 2.5–8.5(–10) cm).
loose, (elongated).
sepals (greenish yellow), lanceolate, 6–8.5 mm, (saccate and cucullate);
petals spatulate to narrowly oblanceolate, 7–10(–12) mm.
sepals elliptic or broadly ovate, 3–6.5(–8) mm, (median pair slightly thickened apically, cucullate);
petals (yellow to orange), broadly obovate, 6–11 mm, (narrowing gradually to short claw).
(divaricate, straight), 5–11(–15) mm, (rigid, fruits not pendent on arching pedicels).
(usually divaricate-spreading, sometimes horizontal or shallowly recurved, straight or slightly curved), (7–)10–20(–25) mm, (slender or 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).
(stipitate or subsessile, gynophore 1–2 mm), globose, subglobose, obpyriform, or obovoid, not or slightly inflated, 3–9 mm;
valves (not retaining seeds after dehiscence), glabrous throughout or sparsely pubescent inside;
replum as wide as or wider than fruit;
ovules 8–20(–28) per ovary;
style 2–4.5 mm.
slightly flattened, (ovate).
slightly flattened.
Physaria newberryi
Physaria gracilis
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.
