| ABSTRACT Elaiophores are floral glands that secrete non-volatile oils as a reward for their pollinators. Their secretions mediate a specialized interaction between oil-producing plants and a few species of oil-collecting bees - Apidae and Melittidae. The present review focuses on the morphological and functional aspects of these secretory structures. We also provide information on their chemistry and pollination ecology. Our survey is organized taxonomically among the plant families for which elaiophore occurrence has been confirmed -for the monocots, Iridaceae and Orchidaceae, and for the eudicots, Calceolariaceae, Cucurbitaceae, Krameriaceae, Malpighiaceae, Plantaginaceae, Primulaceae, Scrophulariaceae, Solanaceae and Stilbaceae. Most oil flowers are... |

| ABSTRACT Collection of pollen was verified in 248 samples of the material on the hind tibial scopae of the solitary bee, Epicharis rustica (Olivier, 1879) captured on their return to the nest. Of the total, 54% (133) of the samples had material on the scopae, 48 of then had only oil and 85 (64%) had both oil and pollen. For seven weeks, almost all (91%) of the 85,000 the pollen grains were of the tree, Byrsonima sericea DC. In the latter weeks the proportion of this species decreased. Like several other members of the genus, E. rustica is univoltine, oligolectic and nests in aggregations. |
