Abstract
In Gabon, we investigated the floral morphology and biology of Napoleonaea vogelii (Lecythidaceae), a cauliflorous understory tree of lowland humid rain forest, and made observations on the behavior of insect visitors. The major insects visiting flowers were: a thrips (Ceratothripoides brunneus), a small moth (Glyphipterix sp.), four species of leaf beetles (Gabonia colae, Gabonia sp. undescribed, Macrocoma sp., and Monolepta sp.), three species of weevils (Endaeus sp. 1–3), and two species of ants (Technomyrmex sp. and Monomorium sp.). In TV. vogelii, the flower is quite complex, and we propose a floral morphological definition for complexity. Insect visitors are spatially segregated on the flower. The evolution of the morphology and biology of the flower of N. vogelii is influenced by insect visitors, both pollinating and non–pollinating. The thrips are the likely pollinators of the flower.RESUMES: Au Gabon, nous avons étudié Napoleonaea vogelii (Lecythidaceae), un arbre cauliflore du sous bois de la for○t humide de plaine. Nos recherches ont porté sur la morphologic et la biologic florales. Nous avons observé le comportement des insectes visiteurs, dont les principals espèces sont: un thysanoptère (Ceratothripoides brunneus), un lépidoptère (Glyphipterix sp.), quatre espèces de coléoptères chrysomélides (Gabonia colae, Gabonia sp. non décrite, Macrocoma sp., et Monolepta sp.), trois espèces de coléoptères curculionides (Endaeus sp. 1‐3), et deux espèces de fourmis (Technomyrmex sp. et Monomorium sp.). La fleur de N. vogelii est trés complexe et nous proposons une définition mor‐phologique de la complexityé florale. II existe une ségrégation spatiale des insectes visiteurs dans la fleur. L'évolution de la morphologic et de la biologic de la fleur de N. vogelii est liée aux insectes visiteurs, aussi bien les pollinisateurs que les autres. II est fort probable que les thysanoptères pollinisent la fleur.Keywords
