Abstract

The siliceous valve of Hantzschia is briefly described, preparatory to following its morphogenesis. While Hantzschia is morphologically very different to Pinnularia, there are several subtle but important similarities in detail. Bundles of microfilaments, significant in generating the gliding motion of these cells, line the cytoplasmic fissure of the raphe. Valve morphogenesis in Hantzschia has been followed in live cells and by using transmission electron microscopy. Major re-organization and translocation of individual organelles, and also the nascent wall and its associated system of structural cytoplasmic components, are described. The spindle always forms on the concave side of the cell..
