Mathematical models have been used as evidence concerning the mechanisms of stomatal patterning.

The details of epidermal development, however, provide direct evidence that has been often ignored. Lineages account for at least part of the distance between neighboring stomata.

Interactions are also indicated by developmental observations, which show that interactions modify stomatal development rather than inhibit stomatal initiation.

Models are useful when constrained by the available facts and when they indicate new concepts that account for unexplained phenomena. An example of such phenomena is the remarkable variability of the processes of epidermal development.
