Abstract: The microsporogenesis and the development of male gametophyte of Euphorbia fischeriana were studied in this paper. The results show that the anther has four locules with wall composed of five layers of cells, and the anther development of the species is basic type, the amoeboid tapetum consists of binuclear cells; the cytokinesis in the meiosis of microspore mother cell is simultaneous; tetrads are usually arranged in tetrahedron and a few of them are bilateral symmetry; the mature pollens are elliptic in shape and belong to the three-cell type with three colporates. This article for E. fisheriana biology research and application development accumulation basic data.

Key words: Euphorbia fischeriana, microspore, male gametophyte
