Amphiderm
Definition
An anatomical formation or double cellular envelope found in certain plant organs, characterized by the presence of two distinct protective layers located at the periphery of tissues. In plant morphology, this structural element protects internal structures against water loss or external aggressions in habitats with extreme ecological conditions.
