Senecio congestus of Michigan Flora.
A boreal circumpolar species, ranging south in the Great Lakes region sporadically to Minnesota, northern Wisconsin, and Michigan, where it has been collected only once: on the shore of Lake Michigan northwest of Harbor Springs, Emmet Co., in 1934.
This is a stout-stemmed species perhaps loosely resembling Erechtites hieraciifolius, but with at least the upper leaves ± clasping and the heads radiate (with light yellow rays).
