Abstract
In vitro studies of the ontogeny of stomata of young leaves of Tradescantia virginiana L. showed that: 1) translocation of nuclei, often along long, winding paths took place in companion cell mother cells before the onset of asymmetric mitosis, 2) the reorientation of the entire mitotic apparatus took place during division of quard cell mother cells. Pertinent factors which may play a role in both processes are indicated.
