Abstract

The present is a key to the past, and the pollen-spore microfossils constitute perhaps the only record through geological Time, projecting the continuum of .change in the diversity of flora, phytogeography and plant evolution. The above theme is explained in the light of our understanding of the principles of pollen - spore morphology and of morphological evolution of both the present day plants and fossil "Sporae Dispersae".
