Brackish-Water Algae from the Hawaiian Islands!

of the Territorial Board of Agriculture and Forestry and the University of Hawaii. Manuscript received February 28, 1947. 2 The author completed most of the work on this paper while on the Department of Botany staff, University of Hawaii, and finished the manuscript at the University of California, Berkeley, with the aid of the excellent algal herbarium (cited as U. C. Herb.) and library at the latter institution. MARINE ALGAE FROM the Hawaiian Islands (in older literature, the Sandwich Islands) have been colJected or studied by a few phycologists. Brackish-water species, however, although essentially marine in relationship, have not been systematically studied for this area. The present study of the brackish-water species was begun late in 1943, in connection with a survey co-operatively con5iucted by the University of Hawaii and the Territorial Board of Agriculture and Forestry, on fishponds bordering' the ocean. At first, two , ponds on the island of Oahu were selected for study. In the following year, however, more data and investigation of other ponds seemed desirable. Three additional ponds on Oahu and eight on the island of Molokai were selected and included in the survey. The study of algae, as well as that of animal life, was thus extended to include all these fishponds. It soon became apparent that the variety of algal forms present in the chosen ponds constituted so large a problem that it would be best to enlist the aid of certain specialists.
