Morphological observation of polyembryony in Ophiopogon japonicus (Liliaceae)

During the development of polyembryony in Ophiopogon japonicus (L.f.)Ker-Ga wl, no embryo was differentiated for the first two months after flowering. A meristematic structure appeared at the distal end of the embryo sac from the end of August to early September and developed into a globular embryo. New embryos appeared from within the embryo, which continued to produce add itional embryos until October and resulted in a polyembryo consisting of di fferent-sized embryos.
