The genus Geppellais a small group of tropical and subtropical algae.It was establishedby Boergesen in 1940 on the basis of its uncalciferous frond and its characteristic of annularattachments of the filaments,with G.mortensenii Boergesen as the type of the genus.Sincethen four more species have been described,namely,G.decussata Dawson(1959),G.echino-caulos Cribb(1960),G.yaeyamense Tanaka(1963),and G.japonica Tanaka et Itono(1977).The species G.decussata was reported by Dawson from Isla San Francisco(Gulf of California)and the Marshall Islands,central Pacific,and later removed by Tanaka and Itono(1977)from the genus Geppella because of the absence of blade and of annular attachments of
