Five new taxa in the genus Pinnularia sectio Distantes (Bacillariophyta) from Livingston Island (South Shetland Islands)
The non-marine diatom flora of Livingston Island (South Shetland Islands, Maritime Antarctic Region) is currently under revision. The taxonomy and morphology of all Pinnularia taxa belonging to the section Distantes present in the samples from Livingston Island have been studied. Eleven different Pi...
