Figs 455–460. A population with more protracted subcapitate poles. Figs 461–472. A more lanceolate form corresponding to E. angusta Krammer & Lange-Bertalot with more clearly capitate rounded ends. Figs 473–480. SEM. Figs 473–478. External view of frustules with differing outline and apices but with equivalent ultrastructural morphology. Figs 479–480.
