Flora of North America species comparison

1–6(–10), erect, short-canescent (hairs ascending to appressed).

1–10+, erect (usually simple), rough-puberulent or shortly spreading hirsute, or proximally glabrate.

basal and proximal cauline tapering to long, winged petioles, blades spatulate-ovate to oblanceolate, 20–95 × 7–15 mm, margins crenate to entire, apices acute, faces densely puberulent;

mid and distal cauline (sometimes subtending axillary tufts of lateral branch leaves) sessile, blades linear-oblanceolate, 16–45 × 3–7 mm, reduced distally, margins entire.

basal petioles 1.5–7 mm, blades spatulate to lanceolate or subrhombic, mostly 50–109 × 15–40 mm, bases tapering, glabrous, margins sharply serrate, ciliate, apices acuminate;

mid and distal sessile, blades lanceolate to subrhombic, much reduced distally, margins serrulate becoming entire distally, glabrous.
