Observed on Viola prionantha Bunge the development of megasporogenesis and the formation of female gametophyte,results demonstrated that,Viola prionantha Bunge ovary 1 room early,3 carpels;On the carpel thoracic and abdominal area wall is living the most ovules,the ovule for lives but actually;Side membrane placenta;The megaspore metrocyte process reduces the fission to produce the striation megaspore tetrad,gathered an end the megaspore or the first megaspore has the function.The embryo sac growth is knotweed.
