Abstract
The purpose of this study was to examine how the floral displays and morphology of Oerstedella exasperata affect reproductive success. This species of orchid is typified by extreme variability in both inflorescence and floral characteristics. In particular there is a wide distribution regarding the degree of symmetry observed in the labellum. The degrees of symmetry are characterized by variations within the fringe symmetry and bilateral symmetry. Furthermore, the surface area of the labellum varies greatly within a population. These remarkably diverse phenotypic morphologies and the summation of the floral traits can enhance or reduce the reproductive success of particular species. To test the relationship between floral advertisement and reproductive success, each flower was examined and grouped according to pollinia presence or removal. Results indicated that pollinia removal was not affected by the degree of bilateral or fringe symmetry or by the size of the labellum. Furthermore, within the 100 individuals examined, the asymmetrical trends were considered directional for bilateral symmetry but nondirectional for fringe symmetry.
Resumen
El propósito de este estudio era examinar cómo los patrones de asimetría en los rasgos morfológicos florales de Oerstedella exasperata afecta el éxito reproductivo de esta especie.
