ABSTRACT IT has previously been reported that in several Polypodiaceous ferns the chromatin of the egg stains progressively less intensely with the Feulgen reagent as the egg matures1. In
the mature fixed egg a clear area is visible in the centre in a position corresponding with that earlier occupied by the nucleus; but it is impossible to identify any staining with certainty
or any sharp boundary to the clear area. The condition of the deoxyribonucleic acid in these eggs raises a problem of considerable genetical and cytochemical interest. A similar condition
has been reported in the eggs of some angiosperms2 and animals3. Access through your institution Buy or subscribe This is a preview of subscription content, access via your institution
