Summary
A detailed investigation of the embryogeny ofPaeonia mascula, P. humilis, P. officinalis, P. lutea, P. tenuifolia, P. lactiflora, P. peregrina andP. suffruticosa has shown, that the embryo development conforms unequivocally to the “true polyembryony” type. It was pointed out, that the embryo development ofPaeonia is similar to some other angiosperms, and does not represent a case, which could be compared with certain gymnosperms. The zygote divides to form at first a coenocyte and then an “embryonic mass” (=VorkeimträgerErnsts). From this group of cells several proembryos arise, one of which generally matures into an embryo proper. Two embryos in a seed originate either by “true” or by “false polyembryony”.
