In the vegetative organs of Santolina leucantha Bertol. (Anthemideae), two distinct types of secretory structures are present: Internal secretory ducts and external glandular trichomes. The ducts are variable in morphology and location, depending on the organ in which they are present. The trichomes, however, show the same structure everywhere. In the roots, there are also scattered cells rich in secretion that are distributed in the periphery of the cortical cylinder. The histochemical analysis of the secretion reveals the presence in all the vegetative organs of many important secondary compounds. Vegetative secretory structures are similar to those in the capitulum we have described in a previous paper.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
