Abstract
The antheridium development of Sargassum fulvellum Ag. and S. kjellmanianum Yendo was investigated. The characteristics of meiosis were observed at the first division of the antheridium in both species. The chromosome number observed was 32 in both species. Six divisions were observed during the development of the antheridium, and the first two divisions were meiotic. 64 nuclei were formed in each antheridium, and cytoplasmic cleavage occurred after the final division. The manner of antheridium development in both species is similar to that already reported from Japan for 7 species of the genus Sargassum.
