Abstract:
In the present paper, Dictyota hauckiana is reported for the first time from Vietnam. It was found growing with other marine macroalgae nearshore, at 1-2 m depth in Ninh Hai waters, Ninh Thuan province. Morphological observations and phylogenetic analysis based on the concatenated rbcL and psbA are presented. There are now 13 species of Dictyota known from Vietnam-ese waters.
