The identity of Porphyra columbina Bangiales, Rhodophyta) originally described from the New Zealand subantarctic islands.
Porphyra columbina Mont. (Bangiales, Rhodophyta) was collected in 1840 from the Auckland Islands in the New Zealand subantarctic region. This name has been applied to bladed Bangiales exhibiting a wide range of morphological forms, and found throughout the New Zealand region and in much of the south...
