| Abstract: | In a comparative study of several cultures of species of Scenedesmus, it was determined that some were morphologically quite stable. These included 1 culture each of S. abundans, S. bijugatus and S. quadricauda. Three isolates were pleomorphic. In an axenic culture of one of the pleomorphic organisms one can find coenobia which resemble S. longus, S. abundans, S. bijugatus and S. acutiformis. The value of pure-culture studies is emphasized, and the identification of members of the genus based solely upon microscopic observation of organisms from nature is discouraged. |
