Abstract
Polysiphonia morrowii (Rhodomelaceae, Rhodophyta) is abundant intertidally in spring in the Northwest Pacific. The species occurs in a large part of the North Sea and in Thau Lagoon, France, showing disjointed distributions, where the alga has been probably introduced recently. Using plastid protein‐coding rbcL sequence data from specimens of P. morrowii and putatively related taxa, collected in Korea, Japan and Far‐east Russia, and Chile, we tested the taxonomic position of each taxon. Pairwise divergence and topology of the sequences indicate that the Chilean taxon was identical to P. morrowii and was clearly separated from other related taxa from Chile. The results suggest that P. morrowii is recently anthropogenically introduced from the Northwest Pacific to Chile by boat or by transport with aquacultured organisms. Detailed observations of field‐collected material will probably enable a more realistic evaluation of distribution of P. morrowii to be made in the Pacific Ocean.
