Fallacia emmae sp nov., (Bacillariophyta) a new soil-inhabiting diatom species from the sub-Antarctic Region
Abstract: During a survey of the diatom flora of some caves on Ile de la Possession, the main island of the Crozet archipelago, a small, unusual naviculoid taxon was observed, initially identified as Fallacia lenzii. The new taxon is described as Fallacia emmae but it shows features of two related g...
