Habit | Perennials; caudex simple or branched; densely (silvery) pubescent, trichomes (irregularly radiate), 6–8-rayed, rays furcate or bifurcate, fused at base. | 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 | several from base, prostrate to decumbent, (usually unbranched, rarely branched distally), 1–3 dm. |
several from base, erect or outer ones decumbent or procumbent, (sometimes much-branched distally), to 6 dm. |
Basal leaves | (tufted); blade broadly obovate, 1–2 cm, margins entire or with 1 or 2 broad teeth, (apex rounded to obtuse). |
blade obovate or rhombic, to ca. 2.5 cm, margins usually shallowly dentate, sometimes lyrate-pinnatifid. |
Cauline leaves | blade oblanceolate to nearly oblong, similar to basal, (base cuneate), 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 | (secund), loose, (elongated in fruit). |
usually dense, (several-flowered). |
Flowers | sepals (yellowish), elliptic to lanceolate, (2–)3–4 mm; petals spatulate, (3.9–)5–7 mm. |
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 | (recurved), 6–8(–12) mm. |
(strongly recurved), to 20 mm. |
Fruits | (usually pendent), elliptic to subglobose, usually slightly compressed (latiseptate), 3–4 mm; valves densely pubescent, sometimes with scattered trichomes inside; ovules 4 per ovary; style ca. 3 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. |

Discussion | Of conservation concern. Physaria parviflora is known from the Parachute Creek Member of the Green River Formation, Rio Blanco County. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
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.
