The New Zealand species of Polysiphonia Greville (Rhodophyta)

Abstract

Fifteen species of Polysiphonia are recognised from New Zealand and the outlying islands — Three Kings, Chatham, Bounty, Snares, Antipodes, Auckland, and Campbell Islands. Of these, 11 species are considered to be indigenous including the newly-described P. pernacola N.M. Adams. One species, P. brodiaei, is almost certainly adventive, while P. sertularioides, P. subtilissima, and P. constricta are apparently so. Of the 15 species, 8 belong to the subgenus Oligosiphonia and 7 to the subgenus Polysiphonia.
