Cocconeis californica var. kerguelensis Heiden ( Figure 48 View Figures 39–59 )
Literature: ( Hustedt 1958, p. 143, figs. 96–99 [as Cocconeis curiosa (Hustedt) ]; Riaux-Gobin and Romero 2003, p. 21, figs. 16, 17, pl. 11, figs. 1–11).
Description: Length 14–18 µm, width 9–11 µm, striae 13–15 in 10 µm.
Remarks: In the study area, this species was always found with C. californica var. californica which is the nominate variety. Most of the observed specimens bear very few striae (formed of one areola) on both sides of the axial area near valve poles.
Ecology and distribution: Antarctic marine species, usually found as epiphyte. Rare in Potter Cove.
Cocconeis costata var. hexagona Grunow ( Figure 49 View Figures 39–59 ) Literature: ( Riaux-Gobin and Romero 2003, p. 24, figs. 4, 5, pl. 3, figs. 1–10; Witkowski et al. 2000, p. 104, pl. 35, figs. 14, 15, pl. 38, fig. 35).
Description: Length 22–27 µm, width 9–12 µm, striae (raphe valve) 14–15 in 10 µm.
Remarks: The transverse fascia of the central area in the observed specimens did not reach valve margin as normally observed in this species ( Riaux-Gobin and Romero 2003).
Ecology and distribution: Widely distributed marine benthic and epiphytic species, Reported from the Arctic ( Hsiao 1980). Rare in Potter Cove.
