dc.description.abstract | The floral biology and reproductive phenology of Langsdorffia hypogaea were investigated. Flowering is annual and high synchronicity was observed along two years, with significant correlation with rainfall. The post-reproductive death of rhizomes suggests monocarpy. Flowers have anthers with extrorse dehiscence and a stigma exposed above the perigonium, and are arranged in dense inflorescences which produce extrafloral nectar. A total of 259 floral visitors were observed, mostly Hymenoptera/Formicidae (149 individuals, 17 ant species), and eight species of Araneae. Although ants were frequent floral visitors, a Coleoptera (Nitidulidae, Stelidota; 28% of total visits) species was the most abundant pollinator. In consequence of herbivory only 12.5% of all inflorescence clusters fruited, and we could not evaluate the percentage of pollinated plants due to insect damage. By being a rich resource in a season of scarcity, activity on inflorescences of L. hypogaea of both pollinators and herbivores was high. | pt_BR |
