THE GENUS THALASSIOSIRA (BACILLARIOPHYCEAE): MORPHOLOGY OF HETEROVALVATE RESTING SPORES OF T. SCOTIA
Resting spores of Thalassiosira scotia Fryx. et Hoban were abundant in phytoplankton net hauls collected from the Scotia Sea south of South Georgia in December 1981. Primary valves are distinguished from secondary valves by the presence of marginal striae with rounded, shoelike protrusions, villi su...
