Perennial herb, from a freely rooted rhizome; stems erect, solitary or occasionally a few clustered together, sparsely long-hairy and often glandular, 15-45 cm tall.
Basal leaves smaller than stem leaves and often deciduous by flowering time; stem leaves opposite, 2-4 (rarely 5) pairs, egg-shaped to elliptic or lance-elliptic, short-stalked below and unstalked above, uppermost ones reduced.
Heads with ray and disk flowers, usually 1-4, rarely as many as 7, the bases hairy and often glandular; involucres 9-15 mm tall; involucral bracts lanceolate, sparsely (usually) to densely long-hairy and often glandular-fringed with small hairs; ray flowers yellow, 12-15, inconspicuously toothed; disk flowers yellow.
Achenes 5-7 mm long, glabrous or sparsely hairy; pappus tawny to brownish, more or less feathery.
This "species" is merely a convenient name for a complex series of apparent hybrids involving either A. mollis or A. amplexicaulis and A. cordifolia or A. latifolia (Cronquist 1955). Most of the BC material examined which had been placed under this name is better placed in A. mollis.
If more than one illustration is available for a species (e.g., separate illustrations were provided for two subspecies) then links to the separate images will be provided below. Note that individual subspecies or varietal illustrations are not always available.
