Pollen grain morphology of Bromeliaceae species collected in areas of the Atlantic Rainforest of southeastern Brazil was studied. The following species were analyzed: Aechmea bambusoides, T. stricta Sol., T. gardneri Lindl., T. geminifl ora Brongn. and Vriesea grandifl ora Leme. Light and scanning electron microscopy were used and the species were grouped into three pollen types, organized according to aperture characteristics: Type I -pantoporate pollen grains observed in P. petropolitana, Type II -2-porate pollen grains, observed in the genera Ananas, Aechmea and Quesnelia, and Type III -1-colpate pollen grains, observed in the genera Billbergia, Pitcairnia, Tillandsia and Vriesea. Pollen data led to the construction of an identifi cation key. The results showed that the species analyzed can be distinguished using mainly aperture features and exine ornamentation, and that these characteristics may assist in taxonomic studies of the family.
