Spheres 0.5 to 2.5 μm in diameter with an outer golden matrix and usually one or more internal vesicles were found in certain leaf cells of Spartina alterniflora and were termed vacuolar bodies. Reactions of the vacuolar bodies to osmolality changes indicated that they were permeable to water and NaCl and accumulated NaCl and were relatively impermeable to sucrose. Cytochemical tests and tests on vacuolar body extracts suggested that vacuolar body matrices were composed of compounds tentatively identified as phenolic aldehydes. Microscopic bodies similar to vacuolar bodies in structure, chemical composition, and physical properties were formed from vacuolar body extracts. Vacuolar bodies and bodies formed in vitro have physical properties in common with two types of coacervate bodies. Possible function of these bodies is discussed.
