Basal leaves pinnate with distal leaflets ± distinct, 2–15(–20) × 1–3 cm; petiole 0.5–5 cm, straight hairs common, tightly appressed, 0.5(–1) mm, stiff, cottony hairs absent, glands absent or sparse; primary lateral leaflets (3–)4–6(–8) per side, on distal (1/4–)1/2–3/4 of leaf axis, overlapping to separate, largest ones obovate, 0.5–1.5(–2) × 0.5–1(–1.3) cm, distal (1/2–)2/3 to whole margin pinnately incised 3/4+ to midvein, ultimate teeth 5–10, linear-oblanceolate, 1.5–8(–10) × 1–2 mm, apical tufts less than 0.5 mm, surfaces green to grayish green, not glaucous, straight hairs sparse to common (sparser adaxially), tightly appressed, 0.5 mm, stiff, cottony hairs absent, glands absent or inconspicuous. Cauline leaves 1–3. Inflorescences (1–)3–15(–20)-flowered, loosely cymose, sometimes racemiform. Pedicels 1–4(–5) cm, ± recurved in fruit. Flowers: epicalyx bractlets narrowly elliptic to linear-lanceolate, 2–5(–6) × 0.5–2 mm; hypanthium 3–4 mm diam.; sepals 3–6 mm, apex acute; petals 4–7 × 3–6 mm; filaments 1–2.5 mm, anthers 0.5–1 mm, ?usually ± 1/2 as long as filaments?; carpels 10–20, styles 1.5–2.5 mm.
