Rhamnaceae. It was found that pollen characters (that is, shape, surface of exine and pollen
morphology) P/E ratio were considered as important and were used as tools in the taxonomy
of these species. The present study shows that the flora of the selected species is a stable
one. Pollen morphology varies among these species very considerably. However, genetic
diversity and molecular studies may also be helpful in this regard. It was concluded from this …
