Doellingeria infirma, the cornel-leaf whitetop or cornel-leaved aster, is a perennial forb native to the eastern United States,[2] that produces white composite flowers in late summer.

Doellingeria infirma has a smooth slender 45 to 90 centimeters (18-36 inches) tall stem which is rough and sparingly branched at the summit.

The flower heads are arranged in a terminal flat topped cluster.

Its range stretches from Alabama and the Florida Panhandle north as far as Massachusetts, Ohio and New York State.

Doellingeria infirma is listed as endangered in Massachusetts, and as "historical" in Rhode Island.
