Development of the microsporangium, and the male gametophyte were studied in Diospyros chloroxylon Roxb. and D. virgiana L. The anther wall development is of the Dicotyledonous type and at maturity it consists of the epidermis, fibrous endothecium, 2-3 wall layers and a secretory tapetum which is uniseriate with uni- or binucleate cells. Connective tapetum is also differentiated. Pollen mother cells divide simultaneously and produce tetrahedral tetrads. Cytokinesis is by furrowing. Pollen grains are smooth, tricolporate and two celled at the time of liberation. Rarely 3- nucleate pollen grains are seen. Pollen degenerations are common in D. virginiana.
