Relations of Environmental Change to Angiosperm Evolution During the Late Cretaceous and Tertiaryso, then environmental change must be a significant factor in morphological change in plants. Morphological (used here in the broad sense to include anatomical) change can be equated to evolutionary change, at least relative to the vegetative body of plants.

The systematic and paleontological applications of palynology exploit the complexity and diversity of organization present in pollen grains and spores. Recent advances in palynology, in association wi
