Morphological variation and haplotype diversity of Halimeda macroloba and H. opuntia (Chlorophyta: Halimedaceae) from Southern Vietnam

This present study carried out sample collections along the coast of Southern Viet Nam, including the coast sites, offshore islands, and Spratly (Truong Sa) islands. External morphological and anatomical characteristics of two dominant species, Halimeda macroloba and H. opuntia, were caparisoned. The genetic marker tufA was applied to find the haplotype diversity and network among Vietnamese and worldwide populations.
