A re-evaluation of Palmaria (Palmariaceae, Rhodophyta) in the North-West Pacific
To understand the phylogenetic relationships within Palmariaceae and taxonomic position of the red algal species of genus Palmaria in the North Pacific and North Atlantic, a molecular study was undertaken of Palmaria sensu lato, Halosaccion and Devaleraea species based on sequence data of the nuclea...

These data are in accordance with earlier studies. Nevertheless, more studies are needed to revise the taxonomy of Palmaria hecatensis in order to complete the revision of Palmaria sensu lato and Devaleraea in the northern hemisphere.

To understand the phylogenetic relationships within Palmariaceae and taxonomic position of the red algal species of genus Palmaria in the North Pacific and North Atlantic, a molecular study was undertaken of Palmaria sensu lato, Halosaccion and Devaleraea species based on sequence data of the nuclear ITS and plastid rbc L. The monophyly of the Palmariaceae was confirmed, although the genus Palmaria sensu lato was strongly supported as paraphyletic, comprising two independent clades, one of only P. palmata and the other, species from the North Pacific.
