Habit | Perennials; caudex simple; densely pubescent, trichomes (loosely spreading), 3–5-rayed, rays distinct, furcate (with exceptionally long branches). | 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 | simple from base, erect to decumbent, (slender), 0.6–1.5 dm. |
simple from base, loosely spreading, usually decumbent, (well exserted from basal leaves, often reddish purple), 0.8–2.4 dm. |
Basal leaves | blades obovate to deltate, 1.5–3(–4) cm, margins entire or outer one with 1 or 2 broad teeth. |
blade (erect), spatulate to nearly rhombic, 2.5–5(–9) cm, (base gradually narrowed to petiole), margins entire, (flat). |
Cauline leaves | blade oblanceolate to spatulate, 0.6–1.5 cm, margins entire. |
blade spatulate, similar to basal, margins entire. |
Racemes | loose. |
loose, (elongated, exceeding basal leaves). |
Flowers | sepals (green-yellow, often tinged with purple), elliptic, 3–4.6 mm; petals oblanceolate, 6–8 mm (claw expanded). |
sepals (pale yellow), lingulate to spatulate, 3.5–4 mm; petals narrowly oblanceolate, 4–6 mm. |
Fruiting pedicels | (sigmoid), 5–9 mm. |
(ascending, curved or sigmoid), 4–7 mm. |
Fruits | (depressed), broadly obovate, compressed (angustiseptate), 2–4 mm, (apex slightly bilobed to nearly truncate); valves densely pubescent, trichomes strongly ascending, spreading, long, (appearing fuzzy), pubescent inside; ovules 4 per ovary; style 3–4 mm, (pubescent or glabrous). |
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). |
