Doellingeria umbellata (P. Miller) Nees var. umbellata . Northern Flat-topped White Aster, Northern Tall Flat-topped Aster. Phen: Jul-Oct. Hab: Wet meadows, pastures, bogs, fens, marshes, stream floodplains, roadbanks, to at least 1900 m. Dist: NL (Newfoundland) west to MN, south to e. VA, w. NC, nw. SC (P. McMillan, pers.comm., 2002), n. GA, ne. AL, MS, TN, and KY.

Origin/Endemic status: Native

Taxonomy Comments: The recognition or not of two taxa at either varietal or specific rank remains unsettled; Mohlenbrock (2015) argued for species rank of D. pubens (A. Gray) Rydberg (north and west of our area). Material from NJ to coastal Virginia treated by Fernald (1950) as Aster umbellatus var. brevisquamus is included here for now, based on Sorrie (2022); it needs additional study and may warrant variety rank under Doellingeria umbellata.
