Flora of North America species comparison

1–4, decumbent, ascending, or erect, ca. 1/2 subterranean, glabrous, from single, vertical, deep-seated caudex.

1–5, prostrate, spreading, finely puberulent, from current and/or previous year’s growth, on usually vertical, fleshy rhizome, rooting and forming rosettes at or near tip; rooted rosettes often develop into an erect, fleshy caudex from which new stems are produced.

basal and cauline;

basal: 1–7, palmately compound, leaflets 3–5;

stipules adnate to petiole, forming 2 linear-lanceolate wings, unlobed, margins entire, apex of each wing free, acute;

petiole 4.5–15 cm, glabrous;

blade reniform or ovate to ± orbiculate, 2–5 × 2.5–5 cm, coriaceous, base tapered, leaflets cleft or dissected into 2–3 elliptic, lanceolate, or oblanceolate lobes 2–7 mm wide, margins usually entire, eciliate, apex acute, mucronulate, surfaces glabrous (± glaucous), abaxial surface usually with prominent vein parallel to each margin;

cauline similar to basal except: stipules lanceolate;

petiole 1–5.5 cm;

blade 1–3 × 2–4.5 cm.
