| Abstract: | "Several authors have recently stressed the need to develop an integrative approach in taxonomy, but studies applying such an approach to Mediterranean orchids are scarce. In sexually deceptive orchids from the taxonomically difficult genus Ophrys, pollination is specific and performed by male insects attracted to the flowers by sex pheromone-mimicking floral scents. Floral compounds are therefore of primary importance for reproductive isolation and species delimitations in this genus. In the fly orchid group, molecular, morphological, and ecological characters have been extensively studied, but a comprehensive survey of floral scents is still lacking. In the present study, the blends of floral compounds of its three members, Ophrys insectifera, Ophrys aymoninii, and Ophrys subinsectifera, were extracted and analyzed by gas chromatography-mass spectrometry. A total of 107 compounds were found, with a majority of saturated and unsaturated hydrocarbons. Significant differentiation, both qualitative and quantitative, was found among the three taxa. This result, pooled with those from the literature, forms a comprehensive and congruent dataset that allows us to elucidate the taxonomic rank of the three members of the fly orchid group" |
