Physaria floribunda
Newberry twinpod, Newberry's twinpod
point-tip twinpod
several from base, ascending to erect (arising laterally, unbranched), 0.5–1(–2.5) dm.
several from base, erect or lateral decumbent, (unbranched), 1–2 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 usually winged);
blade broadly oblanceolate, 3–8 cm, margins usually dentate or pinnatifid, rarely subentire, (terminal lobe acute or obtuse, not rounded).
blade linear-oblanceolate to oblanceolate, 1–2 cm, margins entire.
blade spatulate to linear-oblanceolate, 1–3 cm, margins usually entire, rarely toothed, (apex acute).
dense (elongated or not in fruit, 2.5–8.5(–10) cm).
loose (and greatly elongated in fruit) to congested.
sepals (greenish yellow), lanceolate, 6–8.5 mm, (saccate and cucullate);
petals spatulate to narrowly oblanceolate, 7–10(–12) mm.
sepals linear-oblong, 5–7 mm;
petals spatulate, 9–11 mm.
(divaricate, straight), 5–11(–15) mm, (rigid, fruits not pendent on arching pedicels).
(recurved), 6–15 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).
(usually pendent on arching pedicels, less frequently widely divergent), irregular in shape, (base obtuse or slightly cordate, apex deeply and broadly notched), not strongly inflated, 8–11 × 8–12 mm, (papery);
valves retaining seeds after dehiscence;
replum linear-oblong, constricted, 2.5–4 mm, as wide as or wider than fruit, apex obtuse;
ovules 4 per ovary;
style 5–8 mm.
slightly flattened, (ovate).
flattened.
Physaria newberryi
Physaria floribunda
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.
