Flora of North America species comparison

1–5, sparsely to moderately strigoso-puberulent.

1, erect, glabrous proximal to (and usually into proximal portions of) 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 present at flowering, abruptly tapering to winged petioles, blades ovate, 100–200 × 80–120 mm, broadly tapering to truncate or slightly cordate (rarely) bases, margins singly or doubly serrate (teeth 1–3(–6) mm);

mid to distal cauline subsessile to sessile, blades lanceolate, 130–200 × 45–85 mm, progressively reduced distally, margins serrate (teeth 1–3 mm), abaxially glabrous, adaxially scabrous-hispidulous at least along margins.

75–200 in open paniculiform arrays, branches divaricate, ascending to recurved, weakly to strongly secund, to 50 cm, secondary branches less than 3 cm.

40–70, inconspicuously secund on longer branches, appearing fasciculate on shorter branches, borne in variable arrays, mostly narrow elongate and secund, consisting of axillary and terminal racemiform branches, or wider and compound, consisting of multiple array branches, proximally leafy-bracted, branches and peduncles (2.5–)4(–13) cm, hairy.
