Flora of North America species comparison

1–5, sparsely to moderately strigoso-puberulent.

usually single, erect, essentially glabrous basally to hispidulo-puberulent 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 and proximal cauline tapering to long, winged petioles (quickly reduced distally on stems), blades broadly oblanceolate to obovate, 40–150 × 15–50 mm, margins serrate, finely ciliate, apices acute to obtuse, faces glabrous;

mid and distal cauline sessile, blades linear-elliptic, 5–50 × 2–10 mm, margins entire, finely ciliate.

15–350 (1–10 per branch), clustered on short divergent lateral branches in elongate and usually narrowly paniculiform arrays, often interrupted proximally, not secund, sometimes with ascending, straight or arching, elongate branches (like main axis).
