Abstract
On the basis of the variability and location of the secretory tissues in the plant body, the following are suggested: (1) In relation to their surrounding environment, the secretory tissues fulfill two very important ecological functions--protection against herbivores and pathogens and attraction of pollinators. (2) The protective function preceded the function of attraction. (3) The protective secretory tissues are suggested to have expanded during the course of evolution from the leaf mesophyll outside, to the epidermis and its trichomes, and inside the plant body, to the primary and secondary phloem, and, in a few cases, also to the secondary xylem.
