Abstract

The ultrastructure and pollen morphology of monocotyledonous have provided important data for the resolution of taxonomic problems and proved to be of great diagnostic value in the systematics of various groups, helping both in the genus and in interspecific delimitation. In Iridaceae, the sculpture of the exine and the type and number of apertures of pollen grains vary greatly and the palynotaxonomy offers a lot of useful features for taxonomic and evolutionary studies. The study area of this research, the states of Goiás and Tocantins, is included in the biome Cerrado, and in its vegetation is quite common to find representatives of the family Iridaceae. However, the vegetative morphological characters of its representatives are usually very similar. Obtaining other characters such as from the pollen morphology will contribute to the taxonomy of the genus and family as the pollen characters are considered more stable, and become important in the delimitation of species or groups of related species. The data collected from pollen characteristics of the species of the current research will be essential to many studies, especially those related to taxonomic revisions and contribute to the phylogenies that are being developed in our country, especially to the genera Trimezia, Pseudotrimezia and Sisyrinchium.
