Erigeron vagus
''Erigeron vagus'' is a high-elevation species of flowering plant in the daisy family known by the common names rambling fleabane.〔
''Erigeron vagus'' is native to the peaks of the western United States where it lives on talus slopes, sometimes above the tree line but other times in open coniferous forests.〔 It has been found in several locations isolated from each other, in eastern California (Sierra Nevada and White Mountains), southern Utah, southern Colorado, northeastern Nevada (Elko County), and northeastern Oregon (Wallowa Mountains).〔(Biota of North America Program 2014 county distribution map )〕〔(Calflora taxon report, University of California, ''Erigeron vagus'' Payson, rambling fleabane )〕
''Erigeron vagus'' is a small perennial herb reaching a maximum height of about five centimeters (2 inches), forming a taproot and a branched underground caudex. Its stem and small patch of basal leaves are covered with glandular hairs. The inflorescence holds a single flower head per stem, each with hairy, purple-tipped phyllaries lining the underside of the head. Each head contains 25–40 white or pink ray florets surrounding many yellow disc florets.〔(Flora of North America, Erigeron vagus Payson, 1926. Rambling fleabane )〕
