Smith ( Figure 99 ) Literature: ( Krammer and Lange-Bertalot 1988 , p. 25, fig. 17:1, 2, fig. 18.1; Witkowski et al. 2000. p. 396, pl. 201, figs. 7–9). Description: Length 160–165 µm, width 13–14 µm, fibulae 10–11 in 10 µm, striae very fine. Remarks: This species appears very similar to N. obtusa but has denser fibulae and striae. Nitzschia obtusa , however, is a brackish-water species and unlikely to be found in marine habitats. Ecology and distribution: A widely distributed brackish-water species. Rare in Potter Cove.
