Summary
Abstract: Colleters are secretory structures widely distributed in eudicots and with taxonomic value in many\\\\\\\\nfamilies. Although glandular trichomes have been described in some Anacardiaceae species, the chemical char\\\\\\\\nacterization\\\\\\\\nof their secretions is scarce and to date there are no reports on colleters. Light microscopy and\\\\\\\\nscanning electron microscopy were used to study the distribution and structure of colleters on the vegetative buds\\\\\\\\nof Anacardium humile A.St.-Hil., Lithraea molleoides (Vell.) Engl., Spondias dulcis Parkinson, and Tapirira guianensis Aubl.,\\\\\\\\nand to characterize their secretory products histochemically. In all of these Anacardiaceae species, colleters are\\\\\\\\nmulticellular and multiseriate ovoid or club-shaped glandular trichomes of protodermic origin, present on both\\\\\\\\nsurfaces of leaf primordia. They reach the secretory phase at early stages of leaf development, after which they\\\\\\\\ngradually degenerate, become brown, and fall off. Histochemical tests indicate that the secretion within the\\\\\\\\nglandular cells and outside the trichomes is a complex mixture containing mucilage, fatty acids, and phenolic\\\\\\\\ncompounds, which are secretory products that can play an important role in the protection of meristems against\\\\\\\\ndesiccation and attack by pathogens. Therefore, the distribution of these glandular trichomes, their short-life, the\\\\\\\\nchemical nature of their secretions and their presumed functions support their being classified as colleters
