Of conservation concern. Rays of Erigeron untermannii tend to both coil and reflex, emphasizing its apparent close relationship to E. caespitosus. The leaves are often spatulate and glabrous to glabrate abaxially, features more similar to E. radicatus and its close relatives. Hybrid parentage is a reasonable hypothesis.
