Abstract

THE blue-green alga, Cylindrospermum majus Kuetz., forms a characteristic filament with single terminal heterocyst and sub-terminal spore at both ends of the filament. The alga was isolated on Alien and Arnon's nitrogen-free medium1 in axenic cultures. At one stage of the growth cycle most of the filaments of the alga form characteristic spores, which are ellipsoidal with sculptured dark-brown exospore wall.
