Habit | Perennials; caudex simple or branched; densely (silvery) pubescent, trichomes (irregularly radiate), 6–8-rayed, rays furcate or bifurcate, fused at base. | Perennials; caudex branched, (thickened, cespitose); densely pubescent, trichomes 5- or 6-rayed, rays slightly fused at base, furcate or bifurcate, (tuberculate throughout). |
Stems | several from base, prostrate to decumbent, (usually unbranched, rarely branched distally), 1–3 dm. |
few from base, well-exserted from basal leaves, 0.4–1(–1.2) dm. |
Basal leaves | (tufted); blade broadly obovate, 1–2 cm, margins entire or with 1 or 2 broad teeth, (apex rounded to obtuse). |
blade (erect), obovate to orbicular, 1.5–2.5 cm, (base evidently distinct from petiole), margins entire, (folded). |
Cauline leaves | blade oblanceolate to nearly oblong, similar to basal, (base cuneate), margins entire. |
blade spatulate, margins entire. |
Racemes | (secund), loose, (elongated in fruit). |
compact, subumbellate. |
Flowers | sepals (yellowish), elliptic to lanceolate, (2–)3–4 mm; petals spatulate, (3.9–)5–7 mm. |
sepals (pale yellow), 4–5 mm; petals lingulate, 6–7 mm. |
Fruiting pedicels | (recurved), 6–8(–12) mm. |
(ascending, curved to slightly sigmoid), 5–8 mm. |
Fruits | (usually pendent), elliptic to subglobose, usually slightly compressed (latiseptate), 3–4 mm; valves densely pubescent, sometimes with scattered trichomes inside; ovules 4 per ovary; style ca. 3 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). |
Seeds | somewhat flattened. |
