Habit | Perennials; (with a long taproot), caudex usually buried, simple, (enlarged, covered with marcescent leaf bases, crown rosulate and horizontal to somewhat ascending, forming a dense crown at apex of caudex); (silvery) pubescent throughout, trichomes (sessile or stipitate), 5–8-rayed, rays furcate or bifurcate, (rounded to umbonate, strongly tuberculate, less so or smooth over center). | Perennials; caudex simple; densely pubescent, trichomes 5–7-rayed, rays bifurcate or trifurcate. |
Stems | few from base, decumbent, (arising laterally proximal to current season’s leaves), 0.3–0.8 dm. |
several from base, erect or outer usually decumbent toward base, (from below a terminal tuft of mostly erect leaves, unbranched), 1–2 dm. |
Basal leaves | (petiole slender); blade broadly obovate, or deltate to ovate or narrower, 1.5–3.5 cm, (base abruptly to gradually narrowed to petiole), margins entire or obscurely few-toothed, (apex usually obtuse, nearly acute in narrower leaves). |
blade ovate to elliptic, 2–4 cm, (base gradually narrowed to petiole), margins entire, (surfaces densely pubescent with trichome layers). |
Cauline leaves | (2–5 per stem); blade oblanceolate to spatulate, similar to basal, margins entire, (apex acute). |
(remote, proximal shortly petiolate); blade spatulate to oblanceolate, similar to basal, (base often cuneate), margins entire. |
Racemes | loose, (3–6-flowered). |
elongated. |
Flowers | sepals narrowly oblong to linear, 7–9 mm; petals (erect), spatulate, 10–12(–15) mm. |
sepals linear-oblong, 5–7 mm, (lateral pair subsaccate); petals (erect), lingulate, 8–10 mm, (claw barely differentiated from blade). |
Fruiting pedicels | (widely spreading to ascending, slightly curved or straight), 7–11 mm. |
(recurved), 7–10 mm. |
Fruits | (usually purplish in age), didymous, irregular and somewhat angular, not highly inflated, 4–11 × 10–13 mm, (coriaceous, papery, shallowly grooved distally and on sides, tapered and narrowed toward replum, base obtuse to truncate, apex with broad sinus to nearly truncate); valves (retaining seeds after dehiscence), densely pubescent, not silvery; replum elliptic to obovate, as wide as or wider than fruit, base rounded, margins sparsely pubescent or glabrous, apex rounded (with funicles); ovules 4 per ovary; style 5–7 mm, (glabrous). |
(usually pendent, sessile), subglobose, slightly flattened (angustiseptate), 4–5 mm; valves densely pubescent, trichomes somewhat spreading; ovules 8–12 per ovary; style 4–5 mm. |
Seeds | flattened. |
plump, (mucilaginous when wetted). |
