Flora of North America species comparison

1–5+, sparsely to moderately short strigose or villous.

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

basal withering by flowering, petiolate, smaller to much smaller than cauline, blades oblanceolate, margins serrate;

cauline sessile, blades elliptic-lanceolate or -oblanceolate, mid 80–140 × 2.5–4 mm, distally reduced, usually membranous, bases tapering, attenuate, margins sharply toothed along much of length to nearly entire, ciliate, abaxial faces short-pilose along small and large nerves, adaxial short-pilose along larger nerves.

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.
