• Notes: Solidago riddellii is similar to Euthamia graminifolia except the leaves are longer and wider (6” by 1/2” below to 2” by 3/8” above). The inflorescence is similar in shape but smaller, and the fillaries are shorter (3/16”) and round-tipped. Flowering is from mid-August to mid-September, and fruiting begins in late August. S. riddellii is found in wetter habitats, on wet prairies to marshes.
