Abstract

The writer found that very little work has been done on the somatic mitosis of Iris versicolor L. Some interesting accounts of karyokinesis in the root tips of some monocots have been written. Schaffner (1898) made a detailed study of nuclear and cell division in the root tips of the Allium cepa. He observed that the spindle originated from centrospheres, and that the most typical resting nuclei occured some distance back of the tip beyond the actively dividing region. In good stained material the resting nuclei had one or two large nucleoli and a very distinct chromatin net work.
