The development of anther wall layers in Viburnum odoratissimum belonged to dicotyledonous type and the cell wall endothecial layer showed radial thickening during pollen maturation. The tapetum was a secretory type and composed of single nucleate cells. The development of microspores could be divided into seven stages that were stamen primordial stage, microspore mother cell stage, meiosis stage, tetrad stage, vacuolated and free microspore stage, two-cellular pollen grain stage, and pollen maturation and anthesis stage. Microspore mother cells undertook meiosis with cytokinesis simultaneously to produce tetrahedral tetrads enclosed within callose wall. The surface of mature pollen grains was tricoporate with irregular reticulate sculptures.
