Valve morphogenesis in two Surirellae (S. ovalis Brebisson and S. robusta Ehrenberg) is described. Mitosis takes place at the broad end of the cell. After cleavage, a new Microtubule Center (MC) arises near each spindle pole and moves to the adjacent

Bacillaria paxillifera – perhaps better known by its synonym B. paradoxa – is epi-typified with material from close to the type locality. Its morphology – from the living cell and intact colony to the fine structure of the valve and girdle band

Defined by its unique colonial locomotion, Bacillaria paxillifer (O. F. Mull.) Hendey was recognized as a single, pandemic species by many phycologists. However, reinvestigation of colonies from different habitats revealed three distinct groups: (A)

A local strain of the pennate diatom Pinnularia cf. "nobilis" was investigated using cytochemistry and fluorescence and EM techniques. The regular perforation of the chloroplasts of P. "nobilis" and the lack of a typical diatom pyrenoid were confirme

Rod-shaped bacteria were found together with the "secondary chloroplast" in the endoplasmic reticulum (ER) in the pennate diatom Pinnularia. During the host interphase, bacteria bore cavities into the chloroplast and interacted with thylakoids, formi

The ultrastructure of the male gametes of two centric diatom species, Coscinodiscus wailesii and Chaetoceros laciniosus, is described. The species differ in the presence and configuration of certain organelles and structures, e.g. chloroplasts, Golgi
