Pale Indian Plantain
Cacalia atriplicifolia /Aster Family
Many of the white summer composites are unusual; these flowers do not have ray flowers (petals). I found these flowers blooming at Piney Falls State Natural Area in Grandview in mid-July. They can also be found blooming in openings in woods.
