New data to morphology, taxonomy and distribution Eunotia biconstricta (Grunow) Lange-Bert. (Bacillariophyta)

Abstract

This scanning electron microscopy study of vast materials from lakes in Karelia and Western Siberia has shown a significant morphological variability of quantitative (valve length and width, number of striae and areolae in 10 µm) and qualitative (shape of valve and terminal raphe fissures) features. Based on the original and published data, this allowed extending the diagnosis of Eunotia biconstricta and referring some taxa to the synonymy.

Keywords: Bacillariophyta, Eunotia biconstricta, morphology, taxonomy, distribution
