The fossil occurrence of Phyllocladus and two other Podocarpaceous types in Australia

Abstract

Anatomical features which confirm the early Tertiary occurrence of Phyllocladus in Australia have been described. Phyllocladus morwellensis Deane has been more clearly defined; the sporomorph Phyllocladus palaeogenicus has been described and its distribution recorded. A new sporomorph, Trisaccites micropterus, has been established for certain 3-winged fossil pollen grains isolated from Mesozoic and Tertiary deposits. The distribution of the sporomorph Micocachryidites antarcticus Cookson in Australian deposits has been traced.
