Discussion

Variety ciliata has been separated based on having less dense pubescence; W. F. Yates and C. B. Heiser (1979) felt that this is insufficient for taxonomic recognition, noting that the type collection of H. hispida includes both indument forms. Heliomeris hispida appears to be relatively rare.
