Revisiting Potter Cove, King George Island, Antarctica, 12 years later: new observations of marine benthic diatoms Author Al-Handal, Adil Y. Author Torstensson, Anders Author Wulff, Angela text Botanica Marina 2022 Warsaw, Poland 2022-02-23 65 2 81 103 http://dx.doi.org/10.1515/bot-2021-0066 journal article 10.1515/bot-2021-0066 1437-4323 11000147 Navicula cf. perminuta Grunow ( Figures 69, 70 ) Literature:(Busse and Snoeijs 2002, figs. 11–15; Krammer and Lange-Bertalot 1986 , p. 112 , pl. 35, figs. 14–20). Description: Length 11–24 µm, width 4–6 µm, striae 14–16 in 10 µm. Remarks: The species illustrated here is considered as N. perminuta following the literature cited. A wide variation in valve outline and striae density has been observed (Al-Handal and Wulff 2008a) and may not correspond to the original description of the species. Type material has not been examined and therefore the identity of this species remains questionable. Ecology and distribution: A widely distributed marine and brackish-water species. Common in Potter Cove.
