Caudex branches elongate. Stems openly tufted to loosely spaced, (0.3–)0.6–4 dm; base 1–3 mm diam., ± densely septate-glandular. Leaves glabrate or sparsely to ± densely hairy; basal (2–)3–16 cm, leaflet pairs (2–)3–4(–5); terminal leaflet broadly obovate-cuneate to flabellate, 0.2–3(–4) × 0.5–3 cm, teeth single or double, 2–15 per side, apex usually rounded to truncate, sometimes obtuse; cauline 0–2, reduced, leaflet pairs 2–3. Inflorescences 2–40-flowered, not or ± leafy, open, 1/6–3/4(–4/5) of stem, ± wide, branch angles (10–)20–40(–50)°. Pedicels 3–20 (proximal to 40) mm, not or sparsely to moderately short-hairy, predominantly septate-glandular. Flowers opening widely; epicalyx bractlets linear to elliptic, 2–6 × 1–2 mm; sepals spreading, 4–7(–9) mm, apex acute to obtuse, apiculate; petals overlapping or not, spreading, cream-white to pale yellow (red-tinged in var. crumiana), narrowly to broadly obovate, 4–12 × 3–11 mm, longer than sepals; filaments 1–4 mm, anthers 0.7–1.2 mm; styles thickened, 1–1.5 mm.
