An anatomical study was made of the hypertrophy produced in seedlings of corn by treatment with ethyl mercury phosphate. The leaf primordia become much thickened, and develop irregular crenations and lobes. In the leaf primordia and apical meristem of the plumule, cell division is inhibited; the existing cells undergo very great enlargement. Cells of the hypertrophied organs become multinucleate, containing nuclei that range in size from minute micronuclei to very large giant nuclei. The latter are polyploid. The multinucleate condition and the formation of micronuclei and gain nuclei are the result of abnormal, incomplete mitosis. 2 references, 2 figures.
