Flora of North America species comparison

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

1–10(–30+), decumbent to erect, slender, tufted, proximally glabrous or sparsely hairy, densely short-hispido-strigose in arrays.

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 petiolate;

petioles winged, margins ciliate;

blades linear-oblanceolate to spatulate, 10–170 × 3–30 mm, serrate to crenate near apices;

distal cauline sessile;

blades sometimes subclasping stems, ovate to linear-lanceolate, 16–20 × 7–11 mm, margins often distinctly ciliate.

5–160 (2–10+ more per short branch cluster), in narrowly elongate paniculiform arrays, branches usually 1–6 cm (much longer in damaged plants, sometimes 1–3 proximal branches much elongated in undamaged plants), ascending and bearing short terminal racemiform or paniculiform clusters.

4–75(–100+), not secund, in dense, round-topped corymbiform arrays;

branches white villous.
