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; (delicate, short-lived); caudex simple, (sometimes elongated, covered with persistent leaf bases); usually sparsely pubescent, trichomes 7–12-rayed, rays furcate near base. | ||||||||||||||||||||||||
Stems | few to several from base, prostrate to decumbent or erect, 0.5–2(–4) dm. |
simple from base, erect to decumbent, (unbranched, mostly filiform, slender), 1–1.5 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. |
(erect, petiole slender); blades broadly ovate to elliptic, 0.5–1 cm, (base abruptly narrowing to petiole), margins entire. |
||||||||||||||||||||||||
Cauline leaves | (proximal petiolate, distal sessile); blade obovate or elliptic to spatulate, 0.5–2 cm, margins entire. |
(remote, distally shortly petiolate); blade ± spatulate, (base cuneate), margins entire. |
||||||||||||||||||||||||
Racemes | (usually not secund), dense, (sometimes elongated in fruit). |
lax, (elongated, few-flowered). |
||||||||||||||||||||||||
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 (erect), oblong, 3.5–4 mm, (lateral pair not saccate); petals (often fading to light purple apically), spatulate to nearly lingulate, 6–7 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 to widely spreading, filiform, slender), 5–10 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. |
(pendent), globose or subglobose, compressed, 3–4 mm; valves ± densely pubescent; ovules 6–10 per ovary; style ca. 1.5 mm. |

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.).
