The gynoecium and ovule morphogenesis in Cerasus, Microcerasus and Amygdalus was studied. Pseudomonomerous consists of two carpels: a large carpel is fertile (4 ovules are formed in it, ovules only develop, whereas the others stay at primordial stage) and a small sterile carpel (the do not arise). The gynoecium in Cerasus, Microcerasus and Amygdalus may be determined as . The ovule is hemi-anatropous, crassinucellate, unitegmic, characterized by short funiculus, raphe, mesochalase and hypostase. The integument is of dermal-subdermal origin. The and podium in the nucellus in species were studied for a first time. Embryo sac develops by -type. Refs 26.
