In this paper, we review cultural history, mariculture and taxonomic work to date for Porphyra sensu lato (bladed Bangiales) in China. The bladed Bangiales are a red seaweed group with high species biodiversity and economic value. In China, species occur along the length of the coast and are highly integrated into the country’s culture. Chinese people have used the bladed Bangiales as food and pharmaceuticals for about 1700 years with many references to these seaweeds in ancient books. The mariculture of bladed Bangiales in China also has a long history and an industry has been established based on some species, notably Pyropia yezoensis. The scientific study of the taxonomy of the bladed Bangiales in China began in the late 1920s and to date, based on morphological identification, 25 species and five varieties have been recorded for China, of which 12 species are considered to be endemic to the country. The majority of species have distribution data showing evidence of possible changes due to increasing water temperatures along the coast. The global biodiversity of the bladed Bangiales has been revealed using molecular approaches. This points to the need for molecular taxonomy of Chinese material to document species diversity and distribution, particularly as it includes the wild stocks for seaweed cultivation and because coastal habitats are increasingly impacted by the increasing human population and an expanding mariculture industry. There is a considerable body of literature on the bladed Bangiales in China, but much of it is Chinese and in obscure publications, so we review it here for the benefit of readers worldwide.
