Morphological observation and rbcL gene sequence analysis of Grateloupia orientalis (Rhodophyta), a new record of the Hainan province
海南新纪录种东方蜈蚣藻(红藻门)的形态学观察和rbcL基因序列分析

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.
