Erigeron uniflorus; The dwarf fleabane is a smaller fleabane compared to the more common Alpine Fleabane (E. borealis). The best way to distinguish it is by the rounded base of the flowerheads compared to a more tapered base of alpine fleabane flower heads. It grows in mountain slopes. A third species is the Snow Fleabane (E. humilis). This species grows in the high mountains. It can be distinguished by the purple hairs on the flower heads (E. borealis and E. uniflorus have white hairs on the flowerheads).
It is a member of the daisy family (Compositae).
