A sample of "Hopi Indian" maize from an unknown locale in New Mexico was brought into the writer's laboratory for the preparation of sections of the radicle for the study of the histogens. The sample consisted of a mixture of creamy white kernels, black kernels and kernels of intermediate shades of gray. Some of the paraffin ribbon of radicles was discarded because of the presence of a large cavity behind the root cap. The shape and consistent position of the cavity did not resemble the results of faulty infiltration, and a study of finished preparations showed that the cavities are the result of a cytohistological aberration in the meristem. The present report describes the salient features of the abnormality.
