Identification Key
1.  Leaf blades mostly linear and mostly entire, rarely narrowly elliptic or toothed, 1–7(–11) mm wide
1.  Leaf blades obovate, rhombic, to elliptic, entire to toothed, (7–)10–80 mm wide (some blades smaller, especially distal ones or on immature plants)
2
2.  Leaf blade entire or with sharply acute teeth, glands small and inconspicuous under magnification; synflorescence of sessile clusters subtended by normal-sized to slightly reduced leaves
2.  Leaf blade entire or with bluntly acute to obtuse teeth, sometimes somewhat lobate, glands large and usually conspicuous under magnification (less so in older specimens); synflorescence in paniculiform or umbelliform arrays, the arrays pedunculate and not appearing sessile, the individual heads sometimes sessile along the leafless or bracteate central rachis of the paniculiform or umbelliform array
3
3.  All leaf blades entire (marginal teeth extremely rare), the apex broadly subtruncate to subacute or mucronulate, fairly uniform in size and shape, typically only a few markedly reduced immediately below the inflorescence; synflorescence umbelliform; involucre obconic; phyllaries often with a light midvein that bisects the base of the darker medial band; pappus 3–6 mm long in fruit
3.  Usually at least some leaf blades toothed or lobed, rarely all entire, sometimes the distal ones especially entire, the apex narrowly acute to rounded, size and shape typically not uniform, the leaves typically gradually reduced in size towards the inflorescence; synflorescence paniculiform; involucre campanulate; phyllaries without a light midvein or rarely present at the base of the darker medial band; pappus (6.5–)7– 12 mm long in fruit
