| Summary: | Thalassionema nitzschioides (Grunow) Mereschkowsky (Figure 35) Literature: (Scott and Thomas 2005, p. 144, fig. 2.80a–d). Description: Length 31–36 µm, width 2.5–3 µm, striae (single areole) 10–11 in 10 µm. Remarks: Images of this species shown in Scott and Thomas (2005) from Antarctic material appear with rather different lanceolate valves and subcapitate apices and may belong to a different taxon. Valves of T. nitzschioides have almost parallel margins and rounded apices. Heiden in Heiden and Kolbe (1928) described several varieties in material collected from Antarctica based mostly on variations in valve outline. According to Hustedt (1958), these varieties may have no taxonomic validity. In the present work, only the nominate variety is considered. Ecology and distribution: A widely distributed marine planktonic species from the Arctic to Antarctica (Hasle 2001). Rare in Potter Cove.
