Palynofloras from an outlier of North Maslin Sands are Middle Eocene in age. The palynofloras are non-marine and correlate with the Lower Nothofagidites asperus Zone of the Gippsland Basin and the 'Proteacidites pachypolus' Zone of south-central Australia. The sediments overlie a highly weathered bedrock palaeosurface, indicating that a phase of significant weathering occurred prior to the Middle Eocene. A number of selected taxa are illustrated and their distribution in the palynofloras is discussed. Two new species, Proteacidites mildenhallii and 'Proteacidites Parrawirrensis,' are described and one species, 'Rhoipites byfieldensis, is emended.
