Evidence is described for the occurrence of Phyllocladus prior to 23,000 B.P.t in the Dandenong Ranges, and from 9670 B.P. until nearly 1 100 B.P. in western Victoria.The dates when this conifer died out in the mainland vegetation of Victoria are deduced from the level at which the pollen disappears from pollen profiles obtained from peat sediments that have accumulated in volcanic crater lakes and valley bogs.The distinctive pollen of Phylloc ladus has not been identified in the present atmospheric pollen rain on the mainland.
