Abstract:
Porphyra tenera Kjellm. and Po. yezoensis Ueda, two species cultivated as nori in Japan, were transferred to the genus Pyropia J. Agardh on the basis of the molecular phylogenetic analysis. However, valid combinations for their infraspecific taxa, Porphyra tenera var.
tamatsuensis A. Miura and “Po. yezoensis f. narawaensis,” vigorously growing taxa with
elongated blades cultivated in Japan, have never been proposed. The two taxa are clearly
infraspecific in the respective species on the basis of the molecular data. Since Miura (1984)
designated two gatherings on different dates as “holotype” of “Po. yezoensis f. narawaensis”
contrary to the International Code of Nomenclature for algae, fungi, and plants (Melbourne
Code), the name was not validly published. Therefore we propose a new combination:
Pyropia tenera (Kjellm.) N. Kikuchi, Miyata, M. S. Hwang & H. G. Choi var. tamatsuensis
(A. Miura) N. Kikuchi, Niwa & Nakada and a new valid name: Pyropia yezoensis (Ueda) M.
S. Hwang & H. G. Choi f. narawaensis N. Kikuchi, Niwa & Nakada.
