WE have endeavoured to determine the chromosome numbers of certain species of Eucalyptus, using radicles, root tips and anthers. Although clear-cut mitotic figures were obtained with radicles and root tips, consistent with one another under different conditions of fixation and staining, we were not successful in determining the chromosome number with certainty, owing to the tendency of the chromosomes to remain attached to each other throughout the cycle.
