Similar to the more widely distributed S. speciosa but with the heads more widely spaced in a more slender inflorescence and with middle cauline leaves more narrow (0.5-2 cm vs. more than 2 cm wide). Another similar species is S. hispida which has hirsute stems (instead of glabrous below the inflorescence) and deeper yellow flowers. Photographed in southern NJ.
