• Type: "between Cummins and Yeelanna, Eyre Peninsula, 34 deg 11 min 53 sec S, 135 deg 43 min 41 sec E, South Australia, 16 February 1996, D.Nicolle 1682 (holo: AD; iso: CANB, PERTH)."

taxonomic synonym: Eucalyptus calycogona var. spaffordii Blakely legitimate

• Etymology: "Named after the collector of the type [of Eucalyptus calycogona var, spaffordii Blakely], W.J. Spafford..."
• Text: "This taxon was first recognized by Blakely (1934). Unfortunately Blakely cited the type specimen in error as collected by W.J. Stafford instead of correctly W.J. Spafford, and in doing so, named the variety staffordii Blakely. As the taxon is here recognized as a subspecies, the opportunity is taken to correct the name to subsp. spaffordii."
