The study of microspores of different populations of I.coromandelina has revealed that microspores may be monolete or trilete exhibiting considerable variation in size and shape within one and the same sporangium. The perispore may be loose or closely appressed to the exospore. Their surface ornamentation is invariably echinate but the length and the concentration of the spines and their arrangement may differ in different populations.
