branched, (rarely bearing bulbils in place of flowers), 25–85 cm.

simple, 20–50 cm.

in basal rosette and cauline, basal unlobed or 3–5-lobed, never deeply lobed, cauline (2–3+), alternate, often 3–4-lobed, much reduced, similar to basal, (rarely with axillary bulbils);

stipules small, not decurrent on petiole, (margins fimbriate);

petiole usually to 25 cm;

blade green, orbiculate, surfaces hairy.

in basal rosette and cauline, basal mostly 3-lobed, cauline (2–3), 3-foliolate, reduced, similar to basal (except lobes longer);

stipules large, decurrent on petiole base, (margins fimbriate);

petiole to 6 cm;

blade dark green, orbiculate, (base cuneate), surfaces nearly glabrous or sparsely to densely hairy.

1–3, erect, 3–5(–25)-flowered racemes, 2(–3)-branched, (10–85 cm).
