Vesicaria kingii S. Watson, Proc. Amer. Acad. Arts 20: 353. 1885; Lesquerella kingii (S. Watson) S. Watson
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 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. Racemes (usually not secund), dense, (sometimes elongated in fruit). 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. 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). 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. Seeds flattened (sometimes slightly).
Subspecies 7 (7 in the flora): w United States, nw Mexico.
