Guarçoni, [email protected] Abstract We report the first records of Tillandsia kegeliana, T. loliacea, T. paraensis, T. parvispica, T. recurvata, and T. tenui- folia for Maranhão, Brazil. These species were collected in the Amazonian and Cerrado biomes. This work adds new knowledge to the flora of Maranhão and extends the distribution of these species within Brazil. Key words Biodiversity; new record; geographic distribution; taxonomy; bromeliads.
