ABSTRACT
Tropical angiospermous flora of India, very rich in families, genera and species is highly diversified. Similarly the pollen morphology of these plants shows great variation. The Mimosaceae family is chosen for a detailed pollen morphological description for two reasons. The plants belonging to this family are cultivated widely and some of them grow naturally and abundantly in different regions of India and other tropical areas. The chapter examines pollen illustrations of some tropical angiospermous plants, particularly abundant in the Western Ghats. The pollen grains produced in anthers are monads, their polar view shows them to be spheroidal or triangular. They show tricolpate apertural condition where colpi are broad and taper to rounded ends. Pollen are produced in tetrads and released to the air in the same condition after dehiscence of the anther. The central area of individual pollen grains is marked by tubercles, merging into the lateral ridges with completely fused tubercles.
