The chromosome number of 25 Bromeliaceae species from the genera Dyckia, Vriesea, Aechmea, Ananas, Billbergia, Nidularium, Neoregelia, Neoglaziovia, Orthophytum, Portea, Quesnelia and Wittrockia were assessed. All are diploid 2n=50, except for Orthophytum albopictum and Neoglaziovia variegata, both tetraploids, 2n=100. The chromosome counts are the first report for 19 of the 25 species evaluated. All chromosome counts reinforce x=25 as the basic number for the family.
