Habit | Perennials; caudex simple, (usually woody); densely pubescent, trichomes (sessile or short-stalked), several-rayed, rays simple or furcate, (smooth or tuberculate). | Biennials or perennials; (short-lived); caudex branched; densely pubescent, trichomes (sessile or short-stalked, simple or not), 5–9-rayed, rays furcate, (fine, smooth or finely tuberculate). |
Stems | simple from base, erect, (unbranched, sparsely leaved), to 7 dm. |
several from base, erect or outer ones decumbent or procumbent, (sometimes much-branched distally), to 6 dm. |
Basal leaves | blade elliptic or obovate to oblong, 4–15 cm, margins entire, dentate, or lyrate-pinnatifid. |
blade obovate or rhombic, to ca. 2.5 cm, margins usually shallowly dentate, sometimes lyrate-pinnatifid. |
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 shortly petiolate, distal sessile); blade obovate to rhombic or oblanceolate, 2–4(–6) cm, margins entire or shallowly and remotely dentate. |
Racemes | dense or slightly elongated. |
usually dense, (several-flowered). |
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 ovate or oblong (tapering at base), 3.6–4.8(–5.3) mm, (lateral pair subsaccate, median pair thickened apically, cucullate); petals obovate to spatulate, 4.5–7.5 mm, (blade narrowed to broad claw, margins sinuate). |
Fruiting pedicels | (spreading or recurved, loosely sigmoid), 5–25 mm. |
(strongly recurved), to 20 mm. |
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. |
(± pendent), ovoid, obcompressed, or globose, compressed, 4–6(–8) mm; valves (not retaining seeds after dehiscence), sparsely pubescent or glabrous, sparsely pubescent inside; replum as wide as or wider than fruit; ovules usually 4, rarely 6, per ovary; style 2.5–3.6 mm. |
Seeds | flattened. |

Phenology | Flowering Mar–Oct. | Flowering Jun–Aug. |
Habitat | Rocky draws, canyons, stony hills, ridges, rock crevices on limestone ledges, lava cliffs, sand and gravel of dry stream beds, rocky slopes, talus, shade of bushes or cactus clumps | Open sites and bare areas in rocky limestone soil in mountains, roadbanks, open woods |
Elevation | 400-2400 m (1300-7900 ft) | 2000-2800 m (6600-9200 ft) |

Discussion | Of conservation concern. Physaria aurea (known from the Jicarilla and Sacramento mountains) is similar to 35. P. gooddingii, which is found farther west in the mountains of Catron and Sierra counties, New Mexico, and Greenlee County, Arizona.
