Journal ArticleDOI
Patterns of reproductive isolation in mediterranean deceptive orchids
TL;DR: Comparison of evolutionary rates showed that the contribution of postmating barriers was more relevant in the food-deceptive species than in the sexually deceptive species, whereas premating barriers are most important in sexually deceptive orchids.
Journal ArticleDOI
Chemical and ethological studies of pollination in the genus Ophrys (Orchidaceae).
TL;DR: Ethological field tests indicated chemical mimesis in certain pollinator systems and chemical similarities were found between the volatiles released from Ophrys flowers and the insect glands in a number of pollination systems.

Friends or Relatives? Phylogenetics and Species Delimitation in the Controversial European Orchid Genus Ophrys
Dion S. Devey,Dion S. Devey,Richard M. Bateman,Richard M. Bateman,Michael F. Fay,Julie A. Hawkins +5 more
TL;DR: Heterogeneous copies of the nuclear ITS region show that some putative Ophrys species arose through hybridization rather than divergent speciation, suggesting that the genus has been substantially over-divided at the species level.

Floral isolation is the main reproductive barrier among closely related sexually deceptive orchids

TL;DR: This study quantified floral isolation among three closely related, sympatric orchid species of the genus Ophrys by directly tracking pollen flow, providing the first direct evidence that floral isolation acts as the main reproductive barrier among closely related plant species with specialized pollination.
Journal ArticleDOI
Mimesis of bellflower (Campanula) by the red helleborine orchid Cephalanthera rubra
TL;DR: C. rubra mimics the floral coloration of Campanula in the bee visual system and thereby receives pollination service by the Chelostoma males, phenologically matching and efficiently exploiting the male bee population.
