Summary: | Navicula sp. 2 (Figure 112) Description: Valve elliptic with broadly rounded apices, 9– 12 µm long, 4–6 µm wide. Raphe weakly undulating, proximal raphe endings small and round, terminal endings hooked into same direction and not reaching valve mantle. Axial area elliptic, central area not distinguished from the axial area. Striae radiate, 20–22 in 10 µm, middle striae are shorter. Remarks: This is a very small species which is very difficult to resolve in LM. Ecology and distribution: Marine benthic species. Rare in Potter Cove.
