During an excursion at the District of Rio das Ostras, State of Rio de Janeiro,
January 1978, a new variety of the well known Billbergia pyramidalis was collected. That finding impelled us to do an accurate investigation over the region to obtain more complete data on that new variety. Dried materials deposited in the herbariums of the Botanical Garden of Rio de Janeiro (RB) and DECAN-FEEMA were also examined to provide elaboration of information in preparing this paper. —SeeJ.
