The article presents the results of the study of development of the ovule and female gametophyte in Paeonia anomala L. The possibility of the formation of several embryo sacs in one ovule due to the development of several megasporocytes of the multicellular sporogenous complex and their entry into meiosis is confirmed. From 1 to 4 megasporocytes can enter meiosis, if they are covered by callose. Most often, 2-3 tetrads of megaspores are formed, although further development usually occurs in one tetrad; the rest can remain intact until the late 4-nucleate embryo sac. Possible reasons for the development of a single embryo sac are discussed: competition between tetrads, disruptions in meiosis, mechanisms regulating the fate of cells and the program of their development. Some morphogenetic correlations in the development of the embryo sac and the surrounding structures of the ovule are revealed. In particular, it has been shown that the development of two embryo sacs at the late 4-nucleate stage correlates with partial or complete destruction of the nucellar cap, whereas during the development of one gametophyte it is preserved for a long time. The dynamics of starch in the nucellar tissues during the gametophyte development has been noted: its accumulation first in the cells of the basal part, where the formation of tetrads and a 2-nucleate embryo sac occurs, and then its highest concentration in the lateral parts of the parietal tissue surrounding the growing gametophyte.
