Oogamy in a Centric Diatom


EARLY in October 1947 Melosira varians was found in mass production of auxospores in the Botanical Gardens of Darmstadt in the Darm brook. Material was treated with aceto-carmine and, for want of the normal reagents, mounted via methanol-toluene in ‘Koniferenbalsam’ (Merck). Upon re-examination this spring, only one of the slides proved good enough to allow full analysis of the critical stages preceding auxospore formation. Fortunately it contained an abundance of them.
