. Nova Hedwigia, 141, 201–236.
Abstract: Ile Amsterdam (77\degre 34 E, 37\degre 47 S), a young, small volcanic island situated in the southern Indian Ocean has a very isolated geographic position and is one of the remotest places in the world. The geographic and physical features of the island have resulted in the presence of a very typical diatom (Bacillariophyta) fl ora dominated by species belonging to the genus Pinnularia. A total of 22 different Pinnularia taxa were observed during a taxonomic analysis of aquatic, moss and soil samples. Twelve taxa did not correspond to any of the currently known species and are described as new species. The new taxa are morphologically and ecologically characterized comparing each of them with all at present known species. The other Pinnularia species are briefl y discussed. A comparison with the other sub-Antarctic islands in the southern Indian Ocean clearly demonstrated the unique fl oristic situation of Ile Amsterdam.

Abstract: During a study of the freshwater diatom flora of some hot springs on the sub-Antarctic Kerguelen Islands, an unknown Brachysira species was observed. Detailed morphological analysis using both light and scanning electron microscopy observations revealed sufficient morphological differences to separate this species as Brachysira sandrae sp. nov. The new species belongs to the complex of taxa around B. brebissonii . The type material of Navicula brachysira , most likely the type of B. brebissonii , was studied to reveal its morphological ultrastructure. The new species is compared with B. brebissonii and with similar Brachysira taxa worldwide.
