Identification Key
1. Leaf bases cordate- or auriculate-clasping around the stem
1. Leaf bases not clasping the stem
2
2. Heads axillary in small clusters subtended by leaves 2 times or more as long as the clusters (at least the proximal clusters), occasionally the clusters elongate but then subtended by leaves >6 cm long
3
2. Heads in thyrsiform, racemiform, or paniculiform arrays, the clusters subtended by reduced leafy bracts <6 cm long and subequal to shorter than the clusters
5
3. Stems erect, not glaucous, weakly or not anthocyanic; proximal to mid-cauline leaves broadly lanceolate to elliptic, 3.6–18 cm long, 1–6 cm wide
3. Stems arching, glaucous, strongly anthocyanic; proximal to mid-cauline leaves lanceolate, 5–15 cm long, 0.8–3 cm wide
4
4. Stems strongly arching; proximal midcauline leaves narrowly lanceolate, 5–15 cm long, 0.8–3 cm wide
4. Stems weakly arching; proximal midcauline leaves shorter and broadly lanceolate to rhombic, 5–9 cm long, 1.3–2.4 cm wide
5. Leaves strongly rugose-veined, the lateral and some additional veins prominent and strongly discolorous from the lower surface, impressed on the upper surface
6

8. Basal and proximalmost cauline leaves absent or relatively small, distal cauline leaves spreading to ascending or appressed; leaves sometimes pubescent or scabrous
9
9. Leaves scabrous or hirsute on the upper surface
