Compsopogon in New Zealand

Abstract

Last year a research student. Mr C. F. Hill, of the University of Auckland Botany Department, brought in a mat of bluish green threads which had been caught up with other material on the screens of Ohakuri hydro-electric dam. Microscopic examination showed tint thess threads were a species of the freshwater red-algal genus Compsopogon growing epiphytically upon Myriophyllum and Potaniogeton. Subsequently further material of the same alga was found growing on stones at the outlet of the Meremere power station cooling water on the Waikato River, where the temperature of the water feels appreciably higher than in th; river itself (Fig.I). © Taylor & Francis Group, LLC.
