Habit | Perennials; (somewhat compact); caudex branched, (relatively large); (silvery) pubescent throughout, trichomes (sessile), several-rayed, rays furcate, (slightly umbonate, tuberculate throughout). | 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). |
Stems | several from base, decumbent to ascending (arising laterally, unbranched, stout), (0.2–)0.5–1.7 dm. |
several from base, prostrate, (slender, sparsely pubescent), 0.5–2 dm. |
Basal leaves | (petiole somewhat winged); blades orbicular to obovate, 2–6 cm (width 1–2.5 cm, thick), margins usually repand, rarely entire, (adaxial surface scurfy). |
blade obovate to narrowly elliptic, 1.5–6 cm, margins usually entire, rarely shallowly dentate, (surfaces densely pubescent, often silvery). |
Cauline leaves | blade oblanceolate to broadly spatulate, 1–2 cm (width 3–5 mm), margins entire, (apex obtuse to subacute). |
blade oblanceolate to spatulate, 0.5–1 cm, margins entire, (surfaces often sparsely pubescent). |
Racemes | moderately dense (or elongated). |
(narrow), loose, (elongated in fruit). |
Flowers | sepals linear-oblong, 6–8 mm; petals spatulate, 9–12 mm. |
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). |
Fruiting pedicels | (divergent, straight to somewhat curved or sigmoid), 5–12 mm. |
(ascending to somewhat spreading, straight to slightly curved), 4–8(–12) mm. |
Fruits | (erect), didymous, cordate, moderately inflated, (6–)10–20 × 10–23 mm, (papery, base obtuse or with obscure sinus, apical sinus deep, broad); valves (retaining seeds after dehiscence), densely and loosely pubescent, trichomes spreading; replum linear-oblong, constricted, as wide as or wider than fruit; ovules 4 per ovary; style 4–5(–9) mm. |
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. |
Seeds | plump, (broad). |
