gradually reduced (sessile).
conspicuously bracteate, glabrous or tomentose.
8–13;
corolla laminae 7–10 mm.
40–50+;
corolla tubes 4–5 mm, limbs 3–4 mm.
13–21, green (tips often yellow), 4–9+ mm, glabrous or sparsely tomentose (at least proximally).
conspicuous.
10–30+ in open, corymbiform or subumbelliform arrays.
2–3 mm, glabrous or hirtellous on ribs;
pappi 5–6 mm.
= 46, 92.
Packera multilobata
Packera multilobata is abundant and widespread west of the Continental Divide. Both morphology and habitat vary. In colder parts of its range, plants are shorter, caudices are better developed with clustered stems, and leaf lobes are larger. In desert-like habitats, basal leaves are narrower and more finely lobed, the tomentum is often persistent, and stems are usually single.
