--><span class="statement" id="st-undefined" data-properties="">Perennials; caudex branched, (cespitose); densely (silvery gray) pubescent, trichomes (sessile or subsessile), (4-), 6-, or 8-rayed, rays fused at base, furcate or bifurcate, (slightly umbonate, tuberculate throughout). <b>Stems</b> simple or few to several from base, erect, (unbranched, slender), 0.2–1(–1.5) dm. <b>Basal</b> leaves (densely tufted, not rosulate, reflexed in age); blade obovate to oblanceolate, 0.7–2(–3) cm, margins usually entire, sometimes repand or shallowly dentate, (apex acute). <b>Cauline</b> leaves similar to basal, becoming narrower distally, somewhat reflexed, (distal) blade linear or narrowly oblanceolate, 0.5–2.5(–5.5) cm. <b>Racemes</b> dense, often subcorymbiform. <b>Fruiting</b> pedicels (erect or divaricate-spreading, straight or slightly curved), (3–)5–10(–15) mm. <b>Flowers</b>: sepals (green or greenish yellow), ovate or broadly ovate, 3.5–6.5 mm, (lateral pair subsaccate, cucullate, median pair thickened, slightly cucullate apically); petals (spreading), oblanceolate to obovate, 5.5–8(–10) mm, (claw erect). <b>Fruits</b> (sessile or substipitate), suborbicular to ovoid or ellipsoid, slightly inflated, 4–7 mm; valves pubescent outside, trichomes substipitate, spreading, sometimes sparsely pubescent inside, trichomes sessile, smooth; ovules 4–10(–16) per ovary; style (0.5–)1–2(–4) mm (shorter than fruit). <b>Seeds</b> flattened. <b>2n</b> = 10.</span><!--

|phenology=Flowering Apr–Jun.
|habitat=Sandy and gravelly soils, limey knolls or limestone chip, often in open stands of sagebrush-pinyon, pinyon-juniper, Gambel oak and sometimes ponderosa pine

|discussion=<p>The circumscription of <i>Physaria arizonica</i> here is quite broad and includes plants that have densely tufted basal leaves and relatively few or no cauline leaves; plants that are loosely tufted and have several cauline leaves; and plants that have a strongly branched caudex, leafy stems, and sterile shoots (var. andrusensis). Additional study is needed to understand the pattern of variation in this complex species; all of the characters given above vary considerably.</p>
