Abstract
Isolates from four sites were identified as varieties of the diatom Gomphonema parvulum Kütz. The material was examined by light and electron microscopical techniques. A detailed account of the morphology of this species is given. No fundamental differences between the varieties were found apart from cell shape. It is considered that cell size is of no importance to classification below the species level since reduction in size occurred in all the isolates during normal growth.Keywords
