Habit | Perennials; caudex simple, (usually woody); densely pubescent, trichomes (sessile or short-stalked), several-rayed, rays simple or furcate, (smooth or tuberculate). | Annuals or biennials; without caudex, (cespitose); densely pubescent, trichomes (sessile or short-stalked), few-rayed, rays (ascending or erect), simple or infrequently furcate near base, (long and slender, sometimes with U-shaped notch on one side, smooth or finely tuberculate). |
Stems | simple from base, erect, (unbranched, sparsely leaved), to 7 dm. |
several from base, erect (and stout) or outer ones decumbent, (unbranched or branched, stiff and densely foliate, sterile leaf-bearing branches sometimes present), to 4 dm. |
Basal leaves | blade elliptic or obovate to oblong, 4–15 cm, margins entire, dentate, or lyrate-pinnatifid. |
blade obovate or elliptic, to ca. 3 cm, margins sinuate or shallowly dentate. |
Cauline leaves | (proximal often narrowed to short petiole, distal sessile); blade broadly elliptic to obovate or rhombic, 0.5–3(–5) cm, margins entire. |
(proximal usually shortly petiolate, distal sessile); blade obovate to broadly elliptic, 1–3 cm, margins sinuate or shallowly toothed. |
Racemes | dense or slightly elongated. |
dense, compact, (elongated in fruit). |
Flowers | sepals elliptic to ovate, 3.5–6(–7) mm, (median pair usually thickened apically, cucullate); petals (white, often purple-veined, fading purplish), suborbicular to obovate, obdeltate, or cuneate, 4.5–10(–12) mm, (often narrowed to broad claw, apex emarginate, less frequently claw undifferentiated from blade). |
sepals elliptic or narrowly elliptic or oblong, (3.8–)4.5–5.5 mm, (lateral pair cucullate, very convex, median pair tapering to base, thickened apically, cucullate, often slightly keeled); petals cuneate, 6.5–8 mm, (slightly expanded at base, margins sinuate, apex retuse or entire). |
Fruiting pedicels | (spreading or recurved, loosely sigmoid), 5–25 mm. |
(recurved, curved or sigmoid), somewhat expanded apically. |
Fruits | (pendent or horizontal, sessile or substipitate), subglobose to broadly ellipsoid, not or slightly inflated, (4–)5–8 mm; valves (not retaining seeds after dehiscence), glabrous throughout; replum as wide as or wider than fruit; ovules 4–8(–12) per ovary; style 1–3(–4) mm. |
(sessile or substipitate), oblong or broadly elliptic, compressed (latiseptate), 5–8 mm; valves pubescent, trichomes spreading, sparsely pubescent inside; ovules 4–6 per ovary; style 3–5 mm. |
Seeds | flattened. |
flattened. |

Discussion | Physaria gooddingii (found in the mountains of Catron, Sierra, and western Socorro counties, New Mexico, and in Greenlee County, Arizona) is similar to 9. P. aurea (found farther east), but differs in having trichomes with ascending or erect rays (rather than appressed) and fruits that are strongly latiseptate (rather than not, or very little, compressed), a state that is infrequent in the genus.
