Key message The leaf stomata of some evergreen plants have cuticular rings. According to dynamic modeling, being the ribs of rigidity these rings are able to influence the stomatal mechanics. Abstract The cuticular folds are typical of the leaf surface of many flowering plant species. They are often present on the stomatal complex cells. The functions of such folds are still underinvestigated. This...
Key MessageThe modelling showed that outer ledges prevent wide opening of the stomatal pore and its lifting above leaf epidermis. This stomatal mechanics is combined with xeromorphic features of leaf epidermis. Abstract Methods of light, scanning, and transmission electron microscopy were used to study the stomata of the leaf epidermis in evergreen Acokanthera oblongifolia (Apocynaceae), A. oppositifolia...
