Habit | Perennials; (compact); caudex branched; densely (silvery) pubescent, trichomes (sessile or short-stalked), 5–8-rayed, rays distinct, furcate or bifurcate, (umbonate, tuberculate and the center less so). | 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). | ||||||||||||||||||||||||
Stems | several from base, erect or outer ones decumbent, (unbranched, stout, usually sparsely leaved), 1–3 dm. |
few to several from base, prostrate to decumbent or erect, 0.5–2(–4) dm. |
||||||||||||||||||||||||
Basal leaves | blade linear, 2–7(–10) cm, margins entire, repand, or shallowly dentate. |
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. |
||||||||||||||||||||||||
Cauline leaves | (sessile); blade (erect), spatulate to linear, (1–)2–3(–4.5) cm, margins entire, sometimes involute, (apex acute or subacute). |
(proximal petiolate, distal sessile); blade obovate or elliptic to spatulate, 0.5–2 cm, margins entire. |

Racemes | dense, (exceeding basal leaves). |
(usually not secund), dense, (sometimes elongated in fruit). |
||||||||||||||||||||||||
Flowers | sepals ovate or oblong, (4.5–)5–6(–7) mm, (lateral pair subsaccate, cucullate, median pair thickened, cucullate apically); petals spatulate, 7–9(–11) mm (widened at base, slightly retuse). |
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). |
||||||||||||||||||||||||
Fruiting pedicels | (spreading, sharply sigmoid), 8–15 mm. |
(erect to divaricate-ascending or recurved, erect in distal 1/3, usually sigmoid, sometimes straight or slightly curved), 4.5–10(–15) mm. |
||||||||||||||||||||||||
Fruits | (sessile or substipitate), ovate to oblong, not compressed at distal margins or apex, 5–9 mm; valves sparsely pubescent, trichomes appressed; ovules 4–8 per ovary; style 3–5 mm. |
(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. |

Discussion | Of conservation concern. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
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.).
