| 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。 |

| Abstract: |
| 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 reproductive 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. |
