Discussion

In the United States, Solanum erianthum is common only in central to southern Florida and in extreme southern Texas near the Gulf of Mexico.

The name Solanum verbascifolium Linnaeus has been widely misapplied to S. erianthum (K. E. Roe 1968), but is a synonym of S. donianum that has now been rejected.
