Flora of North America species comparison

1–5, sparsely to moderately strigoso-puberulent.

usually 1, erect, glabrous, sparsely hairy in arrays.

basal petioles 3–5 cm, blades oblanceolate or spatulate to ovate or rotund, 2–4 cm (excluding petioles);

cauline (numerous) subsessile or sessile, blades elliptic or lance-elliptic to ovate, mid mostly 25–50(–65) × 10–25 mm, distal much reduced;

branch leaf petioles 1 mm, blades ovate, 5–15 (excluding petioles) × 2–10 mm.

basal when present similar to proximal cauline;

proximal cauline often withering by flowering, tapering (sometimes rather abruptly) to short, winged petioles, blades ovate-lanceolate, 60–100(–150) × 30–40(–50) mm, thin, margins coarsely serrate, apices acute, abaxial faces hirsute on main nerves, adaxial sparsely hirsute to somewhat scabrous;

mid to distal cauline subsessile to sessile, blades lanceolate, 20–50 × 5–20 mm, gradually reduced distally, margins entire.

linear, 1–3 mm, bracteate.
