T. barbinode of Michigan Flora
In dry to moist soil of open oak forest and savanna, river bluffs, roadsides, borders of wetlands.
Our few specimens have all been annotated as T. chapmanii by B. E. Wofford and D. Estes, which differs from the more southern and eastern T. barbinode in generally being taller, with more dissected and more pubescent leaves, pale yellow-cream flowers, and fruits that are granular-pubescent between the wings. Thaspium barbinode is generally a shorter plant with less dissected and less pubescent leaves, bright yellow flowers, and fruits that are usually nearly smooth between the wings.
