1 to numerous stalked flowers at the tips of branching stems and arising from the upper leaf axils. Flowers are ¾ to 1½ inches across, with 10 to 35 yellow petals (ray flowers) and a small, yellow center disk.
The bracts surrounding the base of the flower are overlapping in 4 to 6 layers; bracts are lance to triangular, green often with a purplish tip, variously hairy and sometimes glandular. Flower stalks are from less than ¼ inch up to nearly 2 inches long, variously hairy and may be glandular.
Leaves and stems:
Leaves are alternate, about 1 inch long and ¼ inch wide, toothless, stalkless, pointed or blunt at the tip, oblong or widest at the tip end and tapering at the base, and often twisted or wavy. Surfaces are variously hairy, from sparse to densely covered in long white hairs, and the color is correspondingly green to gray-green. Stems are multiple from the base, erect, ascending or sprawling but rising at the tips (decumbent), typically branched, green to reddish-brown, sparsely to densely covered in spreading hairs and sometimes glandular.
Hairy False Goldenaster, known in some older references as Chrysopsis villosa, is described by Flora of North America as having 9 distinct varieties, 4 of which have been recorded in Minnesota. Distinguishing characteristics are reported to be leaf shape, degree of hairiness, degree of glandular hairs, number of flower heads and number of florets. Suffice to say that this species is rather variable in those respects.
