with branched inflorescence
Sandy forests (oak, hickory, jack pine, aspen) and clearings; dunes, sandy or rocky plains, rock outcrops and pavements of all kinds; rarely in moist ground.
Ordinarily distinctive in its larger lower leaves, softly pubescent stems and leaves, and glabrous or glabrate achenes. Dwarf, ± glabrous-stemmed forms grow on rock outcrops of the Upper Peninsula (Isle Royale and Drummond Island). Glabrous sand dune plants along the south shore of Lake Superior are S. hispida var. huronensis. Glabrous plants can be difficult to separate from S. simplex, which, however, is always glutinous.
