The plastid ultrastructure of 12 species of Caulerpa (Chlorophyceae) was investigated by the electron microscope. A simpler pyrenoid structure was demonstrated in one species. The conspicuous concentric lamellar bodies, which are characteristic of algae with heteroplasty, were present both in the chloroplasts and the amyloplasts of all the species examined. The possible function and taxonomical value of the bodies were discussed.
