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). | Annuals, biennials, perennials, or subshrubs; eglandular. | ||||||||||||||||||||||||
Stems | few to several from base, prostrate to decumbent or erect, 0.5–2(–4) 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. |
|||||||||||||||||||||||||
Cauline leaves | (proximal petiolate, distal sessile); blade obovate or elliptic to spatulate, 0.5–2 cm, margins entire. |
petiolate, sessile, or subsessile; blade base usually not auriculate (except Paysonia), margins entire, dentate, or sinuate. |
||||||||||||||||||||||||
Racemes | (usually not secund), dense, (sometimes elongated in fruit). |
ebracteate, often 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). |
actinomorphic; sepals erect, spreading, ascending, or reflexed, lateral pair seldom saccate basally; petals white, yellow, lavender, purple, violet, orange, or brown [pink], claw present, often distinct; filaments unappendaged, not winged; pollen (3 or) 4–11-colpate. |
||||||||||||||||||||||||
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. |
|||||||||||||||||||||||||
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. |
silicles or siliques, dehiscent, unsegmented, terete, latiseptate, or angustiseptate; ovules 2–100 per ovary; style usually distinct; stigma entire or strongly 2-lobed. |
||||||||||||||||||||||||
Seeds | flattened (sometimes slightly). |
biseriate, uniseriate, or aseriate; cotyledons accumbent or incumbent. |
||||||||||||||||||||||||
Trichomes | usually short-stalked, subsessile, or sessile, sometimes long-stalked, stellate, scalelike, subdendritic, or forked, sometimes mixed with simple ones. |

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.).
