SUMMARY The development of the carposporophyte of Scinaia pseudojaponica Yamada et Tanaka is described for the first time. The carpogonial branch is 3‐celled. Before fertilization the hypogynous cell divides into a group of 4 cells. Concurrently the cell beneath the hypogynous cells also produces initials which, following fertilization, develop into branched filaments that envelop the carposporophyte. After fertilization the gonimoblast initial is produced laterally from the basal part of the carpogonium. Carposporangia are produced in chains from the free ends of the gonimoblast filaments which grow toward the surface of the thyllus. A very thick pericarp surrounds the mature carposporophyte.
