The male gametophytic plants of Dictyopteris serrata (Arschoug) Hyot have not been reported till date from any part of the world. Gametophytic plants as such in Dictyopteris are rarely document-ted in the literature, due to their infrequent and scanty availability in nature super(1)" super(4). The genus Dictyopteris Lamouroux (Dictyotales, Phaeophyceae) comprises a total of 33 species with worldwide distribution, including the tropical and temperate regions super(5). The characteristic features such as flat, ribbon-shaped, dichotomously branched thallus with more or less prominent midrib and presence of rows of meristematic cells at the thallus apex clearly differentiate it from other genera of Dictyotales, namely Dictyota, Dilophus, Pachydictyon and Spatoglossum super(3). The Indian Ocean species of Dictyopteris has received less attention compared to its allied genus like Dictyota, which has been monographed recently super(6).
