This collection receives many technical visits aiming pollen identification and contributes with numerous monographs, dissertations, theses and papers.
The study of pollen grains, spores and other microscopic palinomorphs, fossils or not, is called palynology. Melissopalinology is the specific study of pollen grains identified on honey samples with the aim of determining plant species visited by bees to produce bee prdocts. This is a valuable tool that can be used in ecological studies on pollination and on botanical origin of bee products and consulting a slides collection of pollen grains is helpful on pollen grains identification.
