Proximal leaves generally glandular, ± thinly long-hairy (woolly) 2. Stem 5–40 cm; heads 1–2; cauline leaves few, abruptly smaller above rosette  A radiating cluster of leaves generally at or near ground level. ; generally alpine or subalpine 3. Phyllaries narrowly oblong  Longer than wide, with nearly parallel sides; wider than linear. , long-tapered; ray flowers 25–60 ..... H. algida 3' Phyllaries oblong to obovate, acuminate  Having a long-tapered, sharp tip, the sides concave. ; ray flowers 12–30 ..... H. nana (2) 2' Stem 30–150 cm; heads 3–15+; cauline leaves gradually smaller distally; montane 4' Ray >= 2 mm wide; yellow 1' Proximal leaves ± woolly or long-soft-wavy-hairy, most hairs glandless 6. Leaves gradually smaller distally; heads 2–5, distal peduncles  Stalk of an individual flower borne singly, not in an inflorescence, or of an entire inflorescence, or the corresponding structure in fruit; the stalk subtending an involucre (e.g., in Asteraceae, Polygonaceae). < 5 cm ..... H. californica 6' Leaves abruptly smaller above rosette; head  1. A dense, often spheric inflorescence of sessile or subsessile flowers. 2. In Asteraceae and some other groups, a head-like inflorescence is one in which sessile or subsessile inflorescence units (e.g., heads in Asteraceae, umbels enclosed by involucres in Eriogonum), instead of individual flowers, are attached in a short dense cluster without an evident axis or branches. generally 1(2), or peduncles generally > 5 cm 7. Leaves generally oblanceolate, sparsely glandular; n California ..... H. nana (2) 7' Leaves generally spoon-shaped, woolly or long-soft-wavy-hairy; s California ..... H. vestita 8. Basal leaf  Organ arising from a stem, generally composed of a stalk (petiole) and a flat, expanded, green, photosynthetic area (blade); distinguished from a leaflet by the presence in its axil of a bud, branch, thorn, or flower; sometimes with lateral, basal appendages (stipules); either simple (toothed, lobed, or dissected but not divided into leaflets) or compound (divided into leaflets). blade  Expanded portion of a leaf, petal, or other structure, generally flat but sometimes rolled, cylindric, wavy, or cupped. entire  Having margins that are continuous and smooth (i.e., without teeth, lobes, etc.). to weakly scalloped, gradually tapered  Gradually (not abruptly) narrower or smaller at base or tip. ; petiole  Leaf stalk, connecting leaf blade to stem; sometimes more or less indistinct. generally <= blade 9' Bracts glandular to barely woolly; stem ± leafy in proximal 1/3 8' Basal leaf blades scalloped to lobed, abruptly tapered, petiole generally >= blade 11' Ray corolla red to orange, 5–10 mm 12. Hairs of abaxial leaf face glandular and glandless; phyllaries generally green, tips tinged red; montane ..... subsp. parryi
