Habit | Perennials; caudex simple, (usually woody); densely pubescent, trichomes (sessile or short-stalked), several-rayed, rays simple or furcate, (smooth or tuberculate). | Perennials; caudex branched, (thickened); densely pubescent, trichomes (sessile), several-rayed, rays furcate or bifurcate, usually fused toward base, (strongly tuberculate). |
Stems | simple from base, erect, (unbranched, sparsely leaved), to 7 dm. |

Basal leaves | blade elliptic or obovate to oblong, 4–15 cm, margins entire, dentate, or lyrate-pinnatifid. |
blade elliptic to lanceolate or obovate, 3–8 cm, margins entire. |
Cauline leaves | (proximal often narrowed to short petiole, distal sessile); blade broadly elliptic to obovate or rhombic, 0.5–3(–5) cm, margins entire. |

Flowers | sepals elliptic to ovate, 3.5–6(–7) mm, (median pair usually thickened apically, cucullate); petals (white, often purple-veined, fading purplish), suborbicular to obovate, obdeltate, or cuneate, 4.5–10(–12) mm, (often narrowed to broad claw, apex emarginate, less frequently claw undifferentiated from blade). |
