Morfologia polínica da vegetação da restinga de algodoal, Pa - IV. famílias anacardiaceae e dilleniaceae

Abstract

The families Anacardiaceae and Dilleniaceae are represented in the restinga vegetation of Algodoal- PA by the species Anacardium occidentale L. Anacardium occidentale L., Anacardium microcarpum Ducke, Tapirira guianenses Aubl., Davilla nítida ( Vahl.) Kub., Doliocarpus spraguei Cheesman and Tetracera willdenowiana Steud. Adult flower buds were taken from the MG herbarium (Museu Paraense Emílio Goeldi) and the pollen grains were acetolyzed, measured and described. The analysis aims to contribute to paleobotany related studies for comparison purposes. It was found that the pollen grains of the species of the Anacardiaceae family are in general medium, isopolar, with a reticulate or striated surface and vary from subprolates to prolates, and those of the species of the Dilleniaceae family are small, isopolar, with a reticulate surface and subprolates.
