    vestiture primarily of long and cottony or sometimes crisped-cottony hairs, glands usually absent or sparse, sometimes common, not red.
    Stems ascending to erect, not flagelliform, not rooting at nodes, lateral to persistent basal rosettes, (0.3–) 1.5–7 (–8) dm, lengths (1–) 1.5–4 (–5) times basal leaves.
    Leaves: basal not 2-ranked;
    cauline (0–) 1–6+;
    primary leaves pinnate to subpinnate (with distal leaflets often confluent), 3–45 (–50) cm;
    petiole: long hairs usually ± to tightly appressed, sometimes ascending, usually stiff, sometimes weak, glands absent or sparse or obscured;
    leaflets (5–) 7–15, on distal (1/6–) 1/5–2/3 of leaf axis, separate to ± overlapping distally, oblanceolate to narrowly obovate, oblong, or cuneate, margins flat, distal 1/4 to whole length, rarely less, usually ± evenly incised 1/4–1/2 or less to midvein, sometimes entire, teeth (0–) 2–18 per side, surfaces similar to strongly dissimilar, abaxial white to ± green, cottony hairs absent or sparse to dense, adaxial green to white, not glaucous, long hairs mostly weak, sometimes stiff.
    Inflorescences (5–) 7–60-flowered, cymose, open.
    Pedicels straight in fruit, 0.3–3 (–6) cm, proximal usually much longer than distal.
    Flowers 5-merous;
    hypanthium 2–7 mm diam.;
    petals yellow, ± obcordate, (3–) 4–10 mm, usually longer than sepals, retuse;
    styles subapical, tapered-filiform, papillate-swollen in proximal 1/5 or less, (1–) 1.5–3 mm.
    Achenes smooth to slightly rugose.
