Flora of North America species comparison

1–5, sparsely to moderately strigoso-puberulent.

1–10+, ascending-erect, glabrous, often short fascicles of leaves present at nodes in axes of distal cauline leaves.

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.

rosettes present at flowering;

basal and proximal cauline tapering to elongate, winged petioles, bases nearly sheathing stems, blades linear-lanceolate, 50–260 (including petiole) × 5–45 mm, somewhat fleshy (fresh), margins entire, faces glabrous;

mid and distal cauline crowded (robust plants), sessile, blades linear-lanceolate to lanceolate, 20–130 × 5–10(–25) mm, reduced distally, margins entire, apices acute to attenuate, glabrous.
