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; (flowering in the first year); caudex branched, (well-developed); densely pubescent, trichomes (subsessile, appressed to spreading), 3–6-rayed, rays furcate or bifurcate, usually slightly fused at base, less frequently distinct. | ||||||||||||||||||||||||
Stems | few to several from base, prostrate to decumbent or erect, 0.5–2(–4) dm. |
few to several from base, ascending (in flower) to nearly prostrate (in fruit), (unbranched), 1–2.5 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 1–3.5 cm); blade ovate to rhombic or rotund, 2–7 cm, (base narrowed abruptly to petiole), margins usually entire, occasionally shallowly repand, (flat). |

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.).
