摘　　要：There were four microsporanges in the mature anther of B. rossica Fedtsch. et Flerov. The development of the anther wall belonged to dicotyledonous type. The tapetum cell was dichotypic. Simultaneous cytocinesis in the microspore mother cells formed tetrad by reduction division and the array of microspore tetrads was different. There were tetrahedron type and bilateral symmetry type. The male gametophyte was 2-cell. The mature pollen was global and tricolporate. All those results were investigated under both light microscope （LM） and electron microscope （EM）There were four microsporanges in the mature anther of B. rossica Fedtsch. et Flerov.
