摘　　要：通过形态结构观察、生殖器官的发育和rbcL序列分析相结合的方法,发现了分布于海南省陵水新村的东方蜈蚣藻(Grateloupia orientalis S.-M.Lin et H.-Y.Liang)为海南新纪录种,该物种具有以下特征:藻体质地凝胶状或软骨质;皮层外部由5～6层念珠状的细胞构成,内部由1～2层星形细胞构成;生殖枝丛由两个分枝组成;果孢子囊分布在除藻体基部外的皮层内。The Grateloupia orientalis S.-M. Lin et H.-Y.Liang collected from Lingshui, Hainan province has been confirmed to be a new record in the Hainan province through morphological observations, development of repro- ductive structures and molecular phylogenetic studies. This species has the following morphological features： Thallus are gelatinous to cartilaginous in texture; cortex is composed of five to six layers of outer moniliform cells and one to two layers of stellate-shape inner cells; ampullae is composed of only two orders of unbranched filament; carposporangia distribute in all the cortex except the bottom of thallus.
