Definition: A gametophyte development stage (PO:0028003) during which the megagametophyte (PO:0025279) develops. Source: POC:Laurel_Cooper, POC:curators
Comment: Although megaspore and megagametophyte development are normally separate, one spore producing one gametophyte, in some flowering plants a single gametophyte may be produced from two or four spores.
