A recent revision of Eucalyptus camaldulensis has recognised a number of subspecies within the species. Three of these subspecies occur within New South Wales: subsp. camaldulensis - Trees with a rough, persistent stocking of bark at the base of the trunk and buds with a distinctly beaked operculum. Leaf venation is sparsely to moderately reticulate. This is the most widespread subspecies in the state and is found throughout the Murray-Darling basin. subsp. arida - Trees with smooth, variegated bark throughout and buds evenly tapering to an obtuse point. Leaf venation is sparsely to moderately reticulate. In New South wales, this subspecies is mostly confined to the western part of the North Far Western Plains. subsp. acuta - Trees with smooth, white to grey bark throughout and buds tapering to an acute to almost acuminate tip. Leaf venation is densely reticulate. In New South wales, this subspecies is mostly confined to an area north from Narrabri.
