Historically, Ophrys morphological taxonomy and species delimitation have been controversial, with treatments inferring from 16 species plus 34 subspecies to as many as 252 species forming 32 complexes. Highly variable, yet possibly convergent, morphologies and paucity of sequence variation have hindered production of a robust phylogenetic framework. This project generated phylogenies and ordinations from nuclear and plastid DNA sequencing, amplified fragment length polymorphism (AFLP) and morphometric data, with the ultimate aims of producing a robust framework as a basis for more rigorous species delimitation and conservation recommendations for the genus. The project also elucidates genetic and morphological relationships within Ophrys section Ophrys, and within the 0. fuciflora and 0. sphegodes aggregates, and assesses the congruence between these contrasting datasets.
