Classification of pollen surf ace patterns of fossil proteaceae , using scanning electron microscope.
Abstract
The scanning electron microscopic study of 41 austrailian fossil pollen soecies , attributed to the family proteaceae, has revealed 11 main surface pattern types , 9 of these patterns are common to the pollen of modern proteaceae; however , 2 surface patterns i.e. scabro-rugulo- foveo-gemmate and scalbro-gemmo- ornate are exclusively present in the fossil proteaceae. The surface patterns in the fossil proteaceae, appearing first in the upper cretaceous and extending to the pilocene, reach greatest diversification in the Eocene with a subsequent decline taking place from Oligocene to pilocene. A new species proteacidites bioporatus is also described.
