The leaf glands of emerged shoots of the water plant Veronica beccabunga were investigated using scanning and transmission electron microscopy as well as cytochemical and vital staining reactions. The glands consist of two glandular head cells surrounded by a mucilage containing polysaccharides and proteins, and one non-glandular stalk cell. The ultrastructure of the head cells is characterized by the presence of a highly developed rough endoplasmic reticulum which shows a close association with the Golgi apparatus, the latter consisting of numerous hypersecretoric dictyosomes. Both these components of the endomembrane system may be involved in a secretional mechanism as has been postulated for protein-secreting animal cells. The two head cells of a senescent gland frequently exhibit different ultrastructural features and distinct vital staining reactions, thus simulating functional heterogeneity. This phenomenon is probably caused by an asynchronous gland cell degeneration accompanied by a discharge of vacuolar tannic substances into the cytoplasm.
