2 subspecies.

Strongly pruinose plants from the St. Arnaud district are included in Eucalyptus tricarpa subsp. decora. There are several other localised forms in Victoria that appear might warrant taxonomic recognition.

Presumed hybrids with E. viridis have been recorded near Inglewood (see E. ×blackburniana).
