Abstract
IN eucalypts the stamens and style of the flower are covered until anthesis by a cap or operculum. Studies of the structure of the operculum have yielded valuable information about relationships within the group and materially assisted in its taxonomy. We describe here the results of further studies on the development of the operculum and show that they lead to a re-appraisal of these relationships and shed light on the evolution of the eucalypts.
