Abstract: 3 figures. 1 table. [Study of specimens from a coastal area (Point Lobos) and an inland site (Hastings) in California. "This study by itself shows significant differences between R. menziesii collected at Point Lobos and that collected at Hastings. These differences exist primarily in the photosynthetic apparatus with almost none found in the respiratory responses." Authors also conlcude, " ... the explanation for the strict coastal distribution of R. menziesii and the explanations of the gradient in its morphology from coastal sites to sites slightly inland may not depend on knowing very much about the details of the responses of gas exchange to the physical environment but rather on factors which have large-scale effects on the magnitude of real growth rates in the field, such as salt exposure, canopy type, and the duration of wetting."]
