The male meiotic cycle in the genus Eucalyptus

Abstract

This investigation was undertaken originally to determine the chromosome number' of various eucalypts. Observations of the course of meiosis have been made in the pollen mother cells of eight species, and, as no work seems to have been carried out on meiosis in Eucalyptus previously, it seemed desirable to place the main results of the investigation on record in view of the important place which the genus occupies in our flora. The account of the meiotic cycle given should be reasonably typical of the process in Tasmanian forms at least.
