The detailed morphological description of the recent Triglochin striata Ruiz & Pav. pollen, widespread in the salt and brackish-water marshes and interdunal depressions, was done using optical microscope and scanning electron microscopes. Pollen morphology analysis provided a possibility to distinguish dispersed Triglochin type pollen from the Holocene sediments. The dispersed Triglochin type pollen was registered in the surface sediments from eight locations in the salt marshes of the estuarine part of the Patos Lagoon, and eleven Holocene samples from core B-2. The obtained results provide the importance of this taxon as a reliable indicator of terrestrial environments with elevated
salinity in the coastal plain of Rio Grande do Sul State.
