The development of sorus of Alaria crassifolia Kjellm., Laminaria japonica Aresch. and Undaria pinnatifida (Harv.) Sur. has been studied. In these species both the zoosporangia and paraphyses originate from the meristoderm of the sporophyll. But, there are some differences in the mode of development of sorus between A. crassifolia and other two species. In L. japonica andU. pinnatifida, the upper cell is destined to be paraphysis and the lower cell to produce zoospore-mother-cells, and zoosporangia and paraphyses develop simultaneously. In A. crassifolia the upper cell is destined to be paraphysis but the lower cell to produce both the paraphysis and zoospore-mother-cells, and the development of zoosporangia takes place secondarily after the complete growth of paraphyses.
