Habit | Perennials; caudex simple, (usually woody); densely pubescent, trichomes (sessile or short-stalked), several-rayed, rays simple or furcate, (smooth or tuberculate). | 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 | simple from base, erect, (unbranched, sparsely leaved), to 7 dm. |
few to several from base, prostrate to decumbent or erect, 0.5–2(–4) dm. |
||||||||||||||||||||||||
Basal leaves | blade elliptic or obovate to oblong, 4–15 cm, margins entire, dentate, or lyrate-pinnatifid. |
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 | (proximal often narrowed to short petiole, distal sessile); blade broadly elliptic to obovate or rhombic, 0.5–3(–5) cm, margins entire. |
(proximal petiolate, distal sessile); blade obovate or elliptic to spatulate, 0.5–2 cm, margins entire. |

Racemes | dense or slightly elongated. |
(usually not secund), dense, (sometimes elongated in fruit). |
||||||||||||||||||||||||
Flowers | sepals elliptic to ovate, 3.5–6(–7) mm, (median pair usually thickened apically, cucullate); petals (white, often purple-veined, fading purplish), suborbicular to obovate, obdeltate, or cuneate, 4.5–10(–12) mm, (often narrowed to broad claw, apex emarginate, less frequently claw undifferentiated from blade). |
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 or recurved, loosely sigmoid), 5–25 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 | (pendent or horizontal, sessile or substipitate), subglobose to broadly ellipsoid, not or slightly inflated, (4–)5–8 mm; valves (not retaining seeds after dehiscence), glabrous throughout; replum as wide as or wider than fruit; ovules 4–8(–12) per ovary; style 1–3(–4) 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 | 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.).
