Physaria newberryi
Physaria navajoensis
Newberry twinpod, Newberry's twinpod
Navajo bladderpod
several from base, ascending to erect (arising laterally, unbranched), 0.5–1(–2.5) dm.
several from base (crowded), erect, not exceeding leaves.
(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).
usually absent.
blade linear-oblanceolate to oblanceolate, 1–2 cm, margins entire.
(petiole not differentiated from blade);
blade linear-oblanceolate, 3–8(–13) mm, margins entire.
dense (elongated or not in fruit, 2.5–8.5(–10) cm).
(secund), dense, corymbose, (few-flowered, not or barely exceeding leaves).
sepals (greenish yellow), lanceolate, 6–8.5 mm, (saccate and cucullate);
petals spatulate to narrowly oblanceolate, 7–10(–12) mm.
sepals (yellow-green), linear to narrowly triangular, 3.7–4.8 mm, (lateral pair subsaccate);
petals (deep yellow, slightly orange in center), spatulate, 5.2–6.5 mm, (claw joined at right angle).
(divaricate, straight), 5–11(–15) mm, (rigid, fruits not pendent on arching pedicels).
(ascending to divaricate-ascending, straight), 3.5–6 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).
(becoming reddish or copper-colored in age), ovate, often slightly compressed (at margins apically), 3–5 mm, (apex acute);
valves (not retaining seeds after dehiscence), glabrous; (septum perforate or not);
ovules 4–8 per ovary;
style 1.8–3 mm.
slightly flattened, (ovate).
plump or slightly flattened, (strongly mucilaginous).
Physaria newberryi
Physaria navajoensis
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 navajoensis is morphologically similar to 85. P. tumulosa of southern Utah, differing subtly. Physaria navajoensis has petals slightly orange at the junction of blade and claw, a sharp bend at that junction giving the flower a flat-topped appearance, and strongly mucilaginous seeds. Physaria tumulosa has pure yellow petals that gently flex at the junction of blade and claw, and seeds that are not mucilaginous. Molecular data (pers. obs.) show that these two species are not directly related. A population of plants on Deer Spring Point, Kane County, Utah, appears to be this species, but molecular data indicate that it is probably a hybrid between P. tumulosa and, most likely, P. intermedia.
