Flora of North America species comparison

1–5, sparsely to moderately strigoso-puberulent.

1 or in clones 2–5+, proximally glabrous or short-strigose 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 (to 100 mm), blades elliptic to obovate or ovate, 80–200 (including petioles) × 25–80 mm, bases broadly to narrowly attenuate, margins serrate, apices acute or obtuse, faces glabrous or sparsely scabroso-strigose;

mid to distal cauline sessile, blades linear-elliptic to elliptic-oblanceolate, 20–60 × 4–20 mm, much reduced distally and usually ascending to appressed, bases tapered, margins entire to sparsely shallowly serrate, ciliate, apices acute.

linear, 1–3 mm, bracteate.

1–4 mm short-strigose, bracteolate.

narrowly campanulate, 3–5 mm.

in 3–4 series, lanceolate, strongly unequal, margins ciliate, apices acute, glabrous.

in 3–4 series, ascending, lanceolate to oblong, strongly unequal, margins finely fimbriate-ciliate distally, midnerves swollen apically, apices broadly acute to obtuse, faces glabrous.

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

50–140, secund on longer branches, less so on apical branches, in open paniculiform arrays, proximal branches ascending and bracteate, apical portions arching.
