The silicoflagellate flora of the Serov area is slightly more abundant; D. frenguellii var. carentis Gleser f. carentis occurs here in large numbers, while D. triacantha var. inermis f. minor Schulz, D. lamellifera Gleser var. lamellifera and D. fibula Ehr. var. fibula f. fibula are less abundant. The Serov flora also includes rare forms such as D. elongata Gleser, D. navicula Ehr., D. triacantha var. inermis Lemm. f. inermis and var. apiculata Lemm. f. apiculata and Naviculopsis robusta FIGURE 7.
