Habit | Perennials; caudex (buried), branched, (not thickened); densely pubescent, trichomes (sessile or short-stalked), 5–8-rayed, rays furcate or bifurcate, (umbonate, rough to finely tuberculate throughout). | Perennials; caudex (buried), usually branched, sometimes simple, (cespitose); densely pubescent, trichomes (appressed), 4–7-rayed, rays distinct, furcate or bifurcate near base. |
Stems | several from base, prostrate, (slender, sparsely pubescent), 0.5–2 dm. |
few to several from base, erect, (unbranched, slender), 0.3–1.5(–3) dm. |
Basal leaves | blade obovate to narrowly elliptic, 1.5–6 cm, margins usually entire, rarely shallowly dentate, (surfaces densely pubescent, often silvery). |
(tufted, erect); blade linear to very narrowly spatulate, 1–3(–4) cm, margins entire (involute). |
Cauline leaves | blade oblanceolate to spatulate, 0.5–1 cm, margins entire, (surfaces often sparsely pubescent). |
similar to basal. |
Racemes | (narrow), loose, (elongated in fruit). |
relatively dense. |
Flowers | sepals (greenish brown, sometimes magenta), linear or elliptic, 4.3–6(–7.5) mm, (median pair thickened apically, cucullate); petals (frequently pink or magenta in distal 1/3–1/2), spatulate to oblanceolate, 6–10(–12) mm, (claw undifferentiated from blade). |
sepals (greenish yellow), elliptic, 3.5–7 mm; petals spatulate, 5–6 mm, (not clawed). |
Fruiting pedicels | (ascending to somewhat spreading, straight to slightly curved), 4–8(–12) mm. |
(ascending, curved or sigmoid), 2–10 mm. |
Fruits | broadly ovoid to suborbicular, inflated, (terete or, often, slightly angustiseptate), 3–6mm; valves sparsely pubescent; ovules usually 4, rarely 6–8 per ovary; style 3–6.5 mm. |
(erect), ovoid (or longer than broad), usually inflated, 4–5 mm, (apex acute, slightly flattened); valves pubescent, trichomes appressed; ovules 4–8 per ovary; style 2–4 mm. |
Seeds | plump. |
flattened, (mucilaginous). |
