Habit | Perennials; caudex simple or branched; densely (silvery) pubescent, trichomes (irregularly radiate), 6–8-rayed, rays furcate or bifurcate, fused at base. | Perennials; caudex simple; densely pubescent, trichomes (often wavy, closely appressed to blade surfaces), 4–5-rayed, rays furcate or bifurcate, slightly fused near base, (tuberculate throughout). |
Stems | several from base, prostrate to decumbent, (usually unbranched, rarely branched distally), 1–3 dm. |
simple from base, loosely spreading, usually decumbent, (well exserted from basal leaves, often reddish purple), 0.8–2.4 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), spatulate to nearly rhombic, 2.5–5(–9) cm, (base gradually narrowed to petiole), margins entire, (flat). |
Cauline leaves | blade oblanceolate to nearly oblong, similar to basal, (base cuneate), margins entire. |
blade spatulate, similar to basal, margins entire. |
Racemes | (secund), loose, (elongated in fruit). |
loose, (elongated, exceeding basal leaves). |
Flowers | sepals (yellowish), elliptic to lanceolate, (2–)3–4 mm; petals spatulate, (3.9–)5–7 mm. |

Fruiting pedicels | (recurved), 6–8(–12) mm. |
(ascending, curved or sigmoid), 4–7 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. |
ellipsoid, not inflated (strongly latiseptate, more so at apex), (3–)5–9 mm; valves pubescent, trichomes closely appressed to surface; ovules 4–8 per ovary; style 2.5–4.5 mm (never more than 1/2 fruit length). |
