Gomesa bifolia (Orchidaceae, Cymbidieae, Oncidiinae) is an epiphytic orchid that presents showy yellow flowers with brown markings on sepals and petals, fragranceless and with oil as reward. The floral biology of this species was studied in cultivated individuals to describe phenology, flower longevity, reproductive system (using manipulative treatment of cross-pollination vs. self-pollination) and floral pollinators. Moreover, direct observations were made on plants exposed outdoors to identify pollinators, describing their foraging behavior and the duration of visits. The results showed that G. bifolia is a mainly self-incompatible, non-autogamous and pollinator-dependent species. The fruit set in manually cross-pollination flowers (100 percent) was higher than the manually self-pollinated flowers (30.8 percent), whereas the control flowers did not set fruits. Females of Centris trigonoides (Apidae, Centridini) were the exclusive pollinators, and the visit rate was low. Several Neotropical orchids of the subtribe Oncidiinae offer floral oils to the pollinators, like the Malpighiaceae familiy. Our results allow inferring that both groups of plants would be part of a guild of species pollinated by oil-collecting bees and that the deceit/pollination syndrome should not be applied to all Oncidiinae flowers. application/pdf issn:0011-6793 http://ri.agro.uba.ar/greenstone3/library/collection/arti/document/2011Torretta spa info:eu-repo/semantics/openAccess openAccess http://ri.agro.uba.ar/greenstone3/library/page/biblioteca#section4 Darwiniana Vol.49, no.1 16-24 http://www.darwin.edu.ar/ FLORAL BIOLOGY OIL-REWARDING FLOWER ONCIDIINAE, REPRODUCTION ANGIOSPERM FLOWER FORAGING BEHAVIOR LONGEVITY PHENOLOGY POLLINATION POLLINATOR REPRODUCTIVE BIOLOGY APIDAE APOIDEA CENTRIDINI CENTRIS TRIGONOIDES CYMBIDIEAE GOMESA MALPIGHIACEAE ONCIDIINAE ORCHIDACEAE Biología reproductiva de Gomesa bifolia (Orchidaceae, Cymbidieae, Oncidiinae) article info:eu-repo/semantics/article info:ar-repo/semantics/artículo publishedVersion info:eu-repo/semantics/publishedVersion |
