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 or, rarely, annuals; caudex simple or branched; ± densely pubescent, trichomes (sessile or short-stalked), few-rayed, rays (usually spreading), distinct or slightly fused at base, furcate or bifurcate, (tuberculate). | ||||||||||||||||||||||||||||
Stems | few to several from base, prostrate to decumbent or erect, 0.5–2(–4) dm. |
simple or few from base, prostrate or straggling to erect, (sometimes purplish, usually unbranched), (0.5–)1–2(–3) 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 oblanceolate, 1.5–5(–7) cm, margins entire or shallowly dentate, (flat). |
||||||||||||||||||||||||||||
Cauline leaves | (proximal petiolate, distal sessile); blade obovate or elliptic to spatulate, 0.5–2 cm, margins entire. |
blade elliptic to linear, (0.5–)1–2.5(–3) cm, margins usually entire. |
||||||||||||||||||||||||||||
Racemes | (usually not secund), dense, (sometimes elongated in fruit). |
(secund), dense, (elongated in fruit). |
||||||||||||||||||||||||||||
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 elliptic or oblong, 4–6(–7) mm, (lateral pair subsaccate, median pair thickened apically, cucullate); petals (often red or lavender when dried), obovate, 6–8.5(–9.5) mm, (narrowing to broad claw). |
||||||||||||||||||||||||||||
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. |
(usually sharply recurved, sometimes divaricate-spreading or nearly horizontal), 5–15(–20) mm, (stout). |
||||||||||||||||||||||||||||
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. |
subglobose, obovoid, or broadly ellipsoid, slightly inflated, (3.5–)4–5.5(–6.5) mm; valves densely pubescent outside, trichomes spreading or closely appressed, rarely sparsely pubescent inside; ovules (4–)8(–10) per ovary; style (slender), 3–5.5(–6.5) 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.).
