Description
Summary:Pithophora is a filamentous green alga of the order Cladophorales (Chlorophyceae). Germination studies of these akinetes (the only reproductive bodies known) were accomplished by several workers but in situ germination in Pithophora kewensis Wittr. was not reported. Germination of akinetes while intact on the green vegetative filaments was an important observation of this study. It was effected by the extension of akinete wall forming a small protuberance, later on growing into a germ tube. The latter was generally formed at right angles to the longitudinal axes of the akinetes and grew to form a filamentous structure following cross wall formation at the base of new cells.
