Habit | Perennials; (relatively diminutive, strongly condensed); caudex (buried), simple or branched, (stout, thatched, thickened with persistent leaf bases); densely pubescent, trichomes (appressed, stiff), 4- or 5-rayed, rays fused at center, (mostly bifurcate). | Perennials; caudex branched, (thickened, cespitose); densely pubescent, trichomes 5- or 6-rayed, rays slightly fused at base, furcate or bifurcate, (tuberculate throughout). |
Stems | simple or few from base, decumbent to ascending, (arising laterally from a tight hemispherical tuft of leaves), to 0.15 dm. |
few from base, well-exserted from basal leaves, 0.4–1(–1.2) dm. |
Basal leaves | similar to cauline, (erect, surfaces silvery). |
blade (erect), obovate to orbicular, 1.5–2.5 cm, (base evidently distinct from petiole), margins entire, (folded). |
Cauline leaves | (ascending, subsessile); blade linear-oblanceolate, (0.6–)0.8–1.3(–1.5) cm, margins entire, (apex acute to narrowly obtuse). |
blade spatulate, margins entire. |
Racemes | strongly congested, (often sessile or nearly so, lateral to leaves). |
compact, subumbellate. |
Flowers | sepals (loosely erect), narrowly oblong, 3–4 mm; petals spatulate, 5–6 mm. |
sepals (pale yellow), 4–5 mm; petals lingulate, 6–7 mm. |
Fruiting pedicels | (erect or ascending, straight to slightly curved), 3–6 mm. |
(ascending, curved to slightly sigmoid), 5–8 mm. |
Fruits | ovate, compressed (latiseptate) on margins and apically, 4–5 mm; valves pubescent, trichomes densely appressed; ovules 4 per ovary; style 1–1.5 mm. |
ovoid to ellipsoid, slightly inflated, (apex not compressed), 3–4 mm; valves pubescent, trichomes erect on mature fruits, (± appearing fuzzy); ovules 8 per ovary; style 4–5 mm, (glabrous). |
