Abstract

In basal medium without a nitrogen source a 3-day-old culture of Scenedesmus obliquus produced zoospores, which were biflagellated, had a parietal chloroplast, lacked a pyrenoid, and were apparently not walled. Identical results were produced with new clones. A reconsideration of the relationships and classification of this organism is now essential.
