Palynological characterization of wood plants from Bosque dos Papagaios, Boa Vista, Roraima, north Brazil. The palynological studies are very important, as they may assist in the identification of botanical species, identification of the pollen of allergic plants, palynotaxonomic studies, identification of fossil landscapes by palynological records contained in sediments and the identification of the botanical origin of honey samples through the pollen content. This study aimed to characterize the pollen types of the woody plants of Parque Ecológico Bosque dos Papagaios, municipality of Boa Vista, Roraima state, Brazil. The collection of botanical material was held every June/2011 to may/2012. Three floral branches were removed from each plant. Of these branches flower buds were submitted to the Erdtman acetolyse method. Twenty five pollen grains were observed for each species to obtain measurements of the polar diameter, equatorial diameter, characterization of exine and openings. Most of the 62 studied species have colporate, medium-sized, prolate spheroidal pollen grains with a striate exine.
