Habit | 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). | Perennials; (delicate, short-lived); caudex simple, (sometimes elongated, covered with persistent leaf bases); usually sparsely pubescent, trichomes 7–12-rayed, rays furcate near base. |
Stems | several from base, erect or outer ones decumbent, (unbranched, stout, usually sparsely leaved), 1–3 dm. |
simple from base, erect to decumbent, (unbranched, mostly filiform, slender), 1–1.5 dm. |
Basal leaves | blade linear, 2–7(–10) cm, margins entire, repand, or shallowly dentate. |
(erect, petiole slender); blades broadly ovate to elliptic, 0.5–1 cm, (base abruptly narrowing to petiole), margins entire. |
Cauline leaves | (sessile); blade (erect), spatulate to linear, (1–)2–3(–4.5) cm, margins entire, sometimes involute, (apex acute or subacute). |
(remote, distally shortly petiolate); blade ± spatulate, (base cuneate), margins entire. |
Racemes | dense, (exceeding basal leaves). |
lax, (elongated, few-flowered). |
Flowers | 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). |
sepals (erect), oblong, 3.5–4 mm, (lateral pair not saccate); petals (often fading to light purple apically), spatulate to nearly lingulate, 6–7 mm. |
Fruiting pedicels | (spreading, sharply sigmoid), 8–15 mm. |
(recurved to widely spreading, filiform, slender), 5–10 mm. |
Fruits | (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. |
(pendent), globose or subglobose, compressed, 3–4 mm; valves ± densely pubescent; ovules 6–10 per ovary; style ca. 1.5 mm. |
