Rhoicosphenia kloseri, light microscope (LM). Girdle view. Fig. 1 is from sample 2009/194. Fig. 2 is from sample 2009/178, and Figs 3–8 are from sample BRM R1272. Figs 1–2. Living cells. Note the single chloroplast inside the cells. Figs 3–8. Size diminution series of cleaned cells. Note the slightly heteropolar cells and how the frustules bend regularly in the shape of the fragment of a circle. Scale bar = 10 μm.	FIGURES 1–8. Rhoicosphenia kloseri, light microscope (LM).
