Jaskowiak, M. A., Phillips, K. A. and Fawley, M. W. Department of Botany, North Dakota State University, Fargo, ND, 58105‐5517 The Sheyenne River is a third order river that flows through central to eastern North Dakota. The first study of this river's periphyton was completed in the summers of 1998‐1999. One hundred sixty diatom species were identified. Navicula and Nitzschia were the most abundant genera. Among this group were three Nitzschia that appear to be new species. These three species were studied extensively using light microscopy. During this examination, one hundred specimens were measured. Preliminary results indicate that Nitzschia sp.1 belongs to the sect. Obtusae and Nitzschia sp. 4 and sp. 5 belong in the sect. Lanceolatae. These specimens will be examined using scanning electron microscopy in a future study.
