The epidermal cells of peony petals immersed for a couple of hours in chlorhydric procaine (of 1000 ppm concentration) undergo a physico-chemical alteration of the colloids in the vacuolar sap. As a consequence, some corpuscle formations, of lipo-proteic nature, appear in the vacuolar sap; in optic micro-scopy they have a hyaline aspect, are strongly refringent and may add the vacuolar dye. Observations carried on in electron microscopy allowed us to make sections through these corpuscles (48 hours after the tissues were introduced in procaine solution) and an electronically dense aspect was remarked. By their sectioning, the corpuscles suffered a surface undulating process. As the procaine accumulates in the cell, an evolution of the corpuscle forming process is obvious, in the course of time. The process becomes stable 48 hours after the treatment is applied; the corpuscles are large and manifest the tendency to anchor in the tonoplast, forming deposits.
