| Perennials; caudex (buried), branched, (thickened with persistent leaf bases, cespitose); densely pubescent (usually grayish-green), trichomes (sessile or short stalked, spreading), several-rayed, rays furcate or bifurcate, slightly fused at base, (tuberculate or finely tuberculate). |
several from base, erect to decumbent, (unbranched, stout, densely leafy sterile shoots sometimes present), (0.5–)4–2.5 dm. |
(clustered at stem base); blade linear to linear-oblanceolate, 2–5 cm, margins entire, usually involute, sometimes flattened, (apex obtuse to subacute). |
blade linear-oblanceolate to linear, 1–3.5(–4.5) cm, margins entire, usually involute. |
compact, (often nearly subumbellate). |
sepals (yellowish or greenish yellow), ovate or oblong, 4.5–7.5(–9) mm, (lateral pair sometimes cucullate, median pair tapering at both ends, thickened apically, cucullate); petals spatulate or oblong, 6.5–10.5(–15) mm, (base sometimes widened, apex rounded or retuse). |
(often expanded distally, ascending or recurved, usually straight or slightly curved, rarely nearly sigmoid), 4–15 mm, (stout). |
(sessile or substipitate), subglobose to slightly ovoid, usually inflated, rarely compressed or obcompressed, 4–6(–10) mm, (apex acute, slightly flattened); valves sparsely pubescent, trichomes appressed; ovules (8–)12–16(–20) per ovary; style (2–)3–4.5(–5.5) mm. |
flattened. |

N. H. Holmgren (2005b) pointed out that the lectotype and other material from New Mexico, where Physaria intermedia is very infrequent, is quite similar to P. parvula from northern Colorado and northeastern Utah; it is also quite similar to, but less robust than, P. pulvinata from southwestern Colorado. The material from Arizona, northwestern New Mexico, and Utah may represent an unnamed taxon; further study is needed. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
