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 usually simple; densely pubescent, trichomes (sessile), rays often furcate, fused toward base, (nearly smooth). | ||||||||||||||||||||||||
Stems | few to several from base, prostrate to decumbent or erect, 0.5–2(–4) dm. |
simple from base, prostrate, (arising lateral to rosette), 0.1–0.5 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. |
blade suborbicular, (1–)2.5(–3) cm, (base abruptly narrowed to petiole), margins entire, (flat), (surfaces densely silvery pubescent, trichomes in multiple layers, appressed). |
||||||||||||||||||||||||
Cauline leaves | (proximal petiolate, distal sessile); blade obovate or elliptic to spatulate, 0.5–2 cm, margins entire. |
(2–4); blade oblanceolate, ca. 1 cm, (base cuneate), margins entire, (apex acute). |
||||||||||||||||||||||||
Racemes | (usually not secund), dense, (sometimes elongated in fruit). |
condensed. |
||||||||||||||||||||||||
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, purplish to greenish), linear-oblong or boat-shaped, 5.5–6.5 mm, (lateral pair more saccate than median); petals (white), spatulate, 9–12 mm, (claw undifferentiated from blade). |
||||||||||||||||||||||||
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. |
(divaricate-ascending, nearly straight), 6–10 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. |
strongly didymous, irregular in shape and size, (base slightly cordate, apex with a deep closed sinus), strongly to somewhat inflated, 6–8 × 6–8 mm (± bladderlike, papery); valves (retaining seeds after dehiscence), pubescent; replum elliptic to obovate, not constricted, as wide as or wider than fruit, apex obtuse; ovules 4–8 per ovary; style 4–5 mm, (sparsely pubescent or glabrous). |

Seeds | flattened (sometimes slightly). |
plump. |

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.).
