The δ^<13>C values for epidermal and mesophyll tissues of two C_3 plants, Commelina communis and Tulipa gesneriana, and a CAM plant, Kalanchoe daigremonliana, were measured. The values for the tissues of both C_3 plants were similar. In young leaves of Kalanchoe. the epidermis and the mesophyll showed δ^<13>C values which were nearly identical, and similar to those found in C_3 plants. However, markedly more negative values for epidermal compared to mesophyll tissue, were obtained in the mature Kalanchoe^^‥ leaf. This is consistent with the facts that the epidermis in a CAM leaf is formed when leaves engage in C_3 photosynthesis and that subsequent dark CO_2 fixation in guard cells or mesophyll cells makes only a small contribution to total epidermal carbon.
