The subject is still very much in its infancy, however, and can perhaps best be put in perspective by considering the fact that more work has been published on the erythrocyte membrane than all the types of plant cell membranes put together. In this volume Douce provides an introduction to the study of chloroplast envelope membranes and supplies fascinating evidence of their complex structure and diverse functions. In 1959 Brownell provided the first definitive evidence that sodium was an essential element for the growth of a flowering plant, Atriplex vesicaria. Subsequent work revealed a situation unique in the mineral nutrition of higher plants, in that sodium was shown to be essential for some species but not others. Brownell and his group went on to show that species possessing the C , pathway of photosynthesis are the ones which require sodium. In this volume Brownell gives an account of this technically exacting line of work and goes on to discuss the recent work from his group which suggests that to understand the biochemistry of sodium action in C , species is likely to prove a difficult problem. Armstrong discusses the development of an electrical analogue model used to solve quantitative problems in the internal movements of oxygen in wetland plants and casts doubt on some of the recent work purporting to show biochemical adaptation to growth under anaerobic conditions. This is the type of study which encourages the hope that physiological work of a good standard is at last infiltrating the field of experimental ecology. Again within the context of a more rigorous analytical ecology, Todd
