ABSTRACT
This study subject to investigate the phenological patterns and floral biology of N. variegate. Observations were accomplished in three populations in Fazenda Aragão, Campina Grande, PB, since May/2004 until April/ 2005. They had been registered data about intensity and duration of phenophases, leaf flushing, flowering and fruiting, and flower morphology, sequence and anthesis duration, concentration and nectar volume. The visitor's behavior was described through direct observations in the field. Neoglaziovia variegata has selfcompatible flowers and the flowering strategy is explosive. The accumulated nectar volume was 5µl, and the concentration is 39%. Chlorostilbon aureoventris is considered effective pollinator specie. The ornitophilous in Bromeliaceae has been possible interpreted as mechanism of parallel evolution between Bromeliaceae and hummingbirds. Neoglaziovia variegata is characterized as one more example of this narrow relationship.
