Habit | Perennials; caudex usually simple, sometimes branched, (not thickened); usually densely pubescent, trichomes (sessile or short-stalked), 3–7-rayed, rays distinct or slightly fused at base, typically furcate near base, bifurcate or 3-partite, (not to slightly umbonate, smooth or moderately to strongly tuberculate). | Perennials; caudex branched, (cespitose); (silvery) pubescent throughout, trichomes several-rayed, rays mostly furcate, (arms of unequal lengths, finely tuberculate). | ||||||||||||||||||||||||||||
Stems | few to several from base, prostrate to decumbent or erect, 0.5–2(–4) dm. |
several from base, erect or lateral decumbent, (unbranched), 1–2 dm. |
||||||||||||||||||||||||||||
Basal leaves | blade suborbicular to narrowly or broadly oblanceolate to broadly elliptic or rhombic, (1.2–)2–6(–8) cm, (base usually abruptly narrowed to petiole), margins entire, sinuate, or lobed. |
(petiole usually winged); blade broadly oblanceolate, 3–8 cm, margins usually dentate or pinnatifid, rarely subentire, (terminal lobe acute or obtuse, not rounded). |
||||||||||||||||||||||||||||
Cauline leaves | (proximal petiolate, distal sessile); blade obovate or elliptic to spatulate, 0.5–2 cm, margins entire. |
blade spatulate to linear-oblanceolate, 1–3 cm, margins usually entire, rarely toothed, (apex acute). |
||||||||||||||||||||||||||||
Racemes | (usually not secund), dense, (sometimes elongated in fruit). |
loose (and greatly elongated in fruit) to congested. |
||||||||||||||||||||||||||||
Flowers | sepals lanceolate, 4–6(–7) mm; petals (yellow, cream-yellow, cream-white, or white), obovate to oblanceolate, 6–13 mm, (claw weakly differentiated from blade). |
sepals linear-oblong, 5–7 mm; petals spatulate, 9–11 mm. |
||||||||||||||||||||||||||||
Fruiting pedicels | (erect to divaricate-ascending or recurved, erect in distal 1/3, usually sigmoid, sometimes straight or slightly curved), 4.5–10(–15) mm. |
(recurved), 6–15 mm. |
||||||||||||||||||||||||||||
Fruits | (sessile or substipitate), subglobose, obovoid, or ellipsoid, compressed (sometimes slightly angustiseptate), 3–9 mm, (rigid, apex truncate, retuse, or rounded-acute); valves sparsely or densely pubescent, sometimes sparsely pubescent inside; (septum sometimes fenestrate, perforate, or obsolete); ovules 4–16 per ovary; style 1–9 mm. |
(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. |
||||||||||||||||||||||||||||
Seeds | flattened (sometimes slightly). |

Discussion | Subspecies 7 (7 in the flora). The Physaria kingii complex is in need of further study. It is widespread in the western United States, mostly in montane environments. This treatment recognizes a highly variable species with generally well-marked, geographically coherent subspecies. Hybridization may be involved in some of the subspecies, especially in subsp. kaibabensis, where molecular data indicate intra-individual genetic variation (pers. obs.).
