| Resumo: |
The pollination ecology of Swartzia apetala Raddi var. apetala was studied in the restinga of Maricá, State of Rio de Janeiro, Brazil. S. apetala var. apetala is a shrub with asynchronic annual blooming, between the months of November and April (hot-rainy season). Each plant can exhibit more than one blooming episode in this period. Their flowers are hermaphrodites, apetalous, heterantherous, odoriferous, and the pollen represents the only reward offered to visitors. It is pollinized by species of Centris and Xylocopa, solitary and polyletic bees, which collect the pollen by means of vibratory movements. Other bees such as Apis mellifera, Pseudaugochloropsis graminea and Trigona spinipes are only pollen-thieves. In this variety of Swartzia vibrating is an efficient method to collect pollen from the anthers despite non-poricidal dehiscence.. The flowering phenology and the behavior of visitors influence the rate of outcrossing.
