Abstract: This paper gives some details on the development of embryo in Matteuccia struthiopteris(L.) Todaro. The first zygote division, splitting the plane perpendicular to the prothallus, and parallel to the longitudinal axis of the archegonium neck; second division plane parallel to the prothallus and perpendicular to the longitudinal axis of the archegonium neck; the third division plane parallel to the longitudinal axis and the prothallus perpendicular to the archegonium neck. When the embryo reaches to the Spherical phase, the outer and outside areas of embryos which develop the first top leaf cell and the first top root cell separately at the same time. These were produced division first leaf primordium and the first root primordium. Subsequently, the first leaf primordium rapidly divides, breaking the cap-like formation and became first young leaves; the first root primordium split slower than the first leaf primordium and speed of the first root grows is slower than the first leaf.

Key words: Matteuccia struthiopteris(L.) Todaro, embryo, development
