Habit | Perennials; caudex simple; densely pubescent, trichomes 5–7-rayed, rays bifurcate or trifurcate. | Perennials; (compact); caudex branched; densely (silvery) pubescent, trichomes (sessile or short-stalked), 5–8-rayed, rays distinct, furcate or bifurcate, (umbonate, tuberculate and the center less so). |
Stems | several from base, erect or outer usually decumbent toward base, (from below a terminal tuft of mostly erect leaves, unbranched), 1–2 dm. |
several from base, erect or outer ones decumbent, (unbranched, stout, usually sparsely leaved), 1–3 dm. |
Basal leaves | blade ovate to elliptic, 2–4 cm, (base gradually narrowed to petiole), margins entire, (surfaces densely pubescent with trichome layers). |
blade linear, 2–7(–10) cm, margins entire, repand, or shallowly dentate. |
Cauline leaves | (remote, proximal shortly petiolate); blade spatulate to oblanceolate, similar to basal, (base often cuneate), margins entire. |
(sessile); blade (erect), spatulate to linear, (1–)2–3(–4.5) cm, margins entire, sometimes involute, (apex acute or subacute). |
Racemes | elongated. |
dense, (exceeding basal leaves). |
Flowers | sepals linear-oblong, 5–7 mm, (lateral pair subsaccate); petals (erect), lingulate, 8–10 mm, (claw barely differentiated from blade). |
sepals ovate or oblong, (4.5–)5–6(–7) mm, (lateral pair subsaccate, cucullate, median pair thickened, cucullate apically); petals spatulate, 7–9(–11) mm (widened at base, slightly retuse). |
Fruiting pedicels | (recurved), 7–10 mm. |
(spreading, sharply sigmoid), 8–15 mm. |
Fruits | (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. |
(sessile or substipitate), ovate to oblong, not compressed at distal margins or apex, 5–9 mm; valves sparsely pubescent, trichomes appressed; ovules 4–8 per ovary; style 3–5 mm. |
Seeds | plump, (mucilaginous when wetted). |
flattened. |
2n | = 16, ca. 20. |
