Abstract
SEVERAL years ago, when certain pollen grains from Tertiary deposits in south-eastern Victoria were referred to the genus Nothofagus1, it was recognized that some of them seemed to be intermediate in form between the two types of pollen grains that normally occur in this genus. At that time these divergent types were believed to be the pollen grains of extinct species of Nothofagus, and, as such, it seemed doubtful whether their exact affinity would ever be determined.
