Discussion

Variety umbellata is common in the central and northern part of its range, becoming less so in the southern Appalachian Mountains and the foothills of northern Georgia and Alabama. More densely pubescent forms occur in the northeastern portion of the range. Minor forms have been described: Aster umbellatus forma convexus Allabach, A. umbellatus forma flexicaulis (House) Fernald, A. umbellatus forma discoideus Victorin (rays present, immature), A. umbellatus forma intercedens Fernald (more pubescent plants), Doellingeria umbellata forma flexicaulis House, and D. umbellata forma intercedens (Fernald) Moldenke.
