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 simple, (not thickened); densely pubescent, trichomes (short-stalked), several-rayed, rays distinct, furcate or bifurcate, (tuberculate, much less so over center, often nearly smooth on lower layer). | ||||||||||||||||||||||||
Stems | few to several from base, prostrate to decumbent or erect, 0.5–2(–4) dm. |
simple from base, spreading or erect, (unbranched), ca. 1 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. |
(petiole long, slender); blade elliptic to obovate, 3–4 cm, (base narrowing to petiole), margins entire. |

Cauline leaves | (proximal petiolate, distal sessile); blade obovate or elliptic to spatulate, 0.5–2 cm, margins entire. |
(shortly petiolate); blade elliptic to obovate, 1–2 cm, margins entire. |

Racemes | (usually not secund), dense, (sometimes elongated in fruit). |
dense. |
||||||||||||||||||||||||
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 narrowly elliptic or oblong, ca. 4.5 mm, (median pair thickened apically, cucullate); petals narrowly spatulate, 7–8 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. |
(sigmoid), 5–8 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. |

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.).

Of conservation concern. Additional research is needed to determine whether Physaria lata is a variant of P. pinetorum, with which it sometimes grows. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
