''Erigeron glabellus'' is a North American species of flowering plants in the daisy family, called the streamside fleabane.〔 ''Erigeron glabellus'' is widespread across much of the colder parts of western North America. In Canada, it has been found in Yukon, Northwest Territories, British Columbia, all 3 Prairie Provinces, and Ontario. In the United States, it grows in Alaska, the northern part of the contiguous USA from Washington to Wisconsin, and in the Rocky Mountains as far south as Arizona and New Mexico.〔(Biota of North America Program 2014 state-level distribution map )〕 ''Erigeron glabellus'' is distinguished from related species by its extremely narrow ray florets, sometimes reduced to thread-like strands. The plant is a perennial herb up to 70 centimeters (28 inches) in height. It sometimes produces only 1 flower head per stem, sometimes a group of up to 10. Each head as many as 175 white white, pink, or blue ray florets surrounding numerous yellow disc florets.〔(Flora of North America, ''Erigeron glabellus'' Nuttall, Gen. N. Amer. Pl. 2: 147. 1818.
