MORPHOLOGY OF THE SYMMETRICAL MORPHOTYPES OF CENTRONELLA REICHELTII VOIGT (FRAGILARIACEAE, BACILLARIOPHYCEAE) FROM PATAGONIAN ENVIRONMENTS

The ultrastructure of symmetrical valves of Centronella reicheltii Voigt, resembling the former C. rostafinskii Woloszynska, is studied for the first time, and their morphology is compared with the asymmetrical forms. Valve morphology and morphometry of both morphotypes are similar and only differ i...
