Abstract
A new ontogenetic classification of stomatal types is proposed which replaces the three ontogenetic types of Pant (1965) with seven new ones. The new classification clearly differentiates between the developmental involvement of the subsidiary cells and the purely structural relationship of the neighbouring cells. All known, and hypothetical, ontogenetic pathways of stomatal development can he incorporated into the new classification. An, hitherto unknown, ontogenetic type which incorporates neighbouring, mesogene subsidiary, and perigene subsidiary cell elements into the stomatal complex is described from the fern, Polypodium vulgare L.
