Abstract

Freshwater algal samples have been collected from four districts of Andhra Pradesh and screened for the Genus Pediastrum. The examination of 40 samples collected revealed a number of rare and noteworthy Pediastrum taxa. In the present paper six varieties of Pediastrum simplex Mayen are depicted and discussed. These are Pediastrum simplex Mayen variety simplex Komarek, Var. clathratum (Schrot) Chod, var. psuedoglabrum Parra, var. sturmii (Reinch) Wolle, var. echinulatum Wittr. Var. biwaense Fukush. Of these former two were more frequent with different morphotypes in all samples and later three were rare in distribution. The taxonomic key is provided and all taxa are described with microphotographs. Pediastrum simplex var. psuedoglabrum Parra, var. sturmii (Reinch) Wolle, var. echinulatum Wittr. Var. biwaense Fukush are reported as first distributional records to the state of Andhra Pradesh.
