For phylotranscriptomic purpose, we sequenced floral transcriptomes for representatives of most of the Ophrys (bee orchids) main lineages.

For phylotranscriptomic purpose, we sequenced floral transcriptomes for 11 representatives of 7 (out of 9) of the Ophrys (bee orchids) main lineages with Illumina technology plus two Himantoglossum species (H. hircinum and H. robertianum that were employed as outgroups). One of the main goal of this study was to investigate the relative contribution of gene flow in Ophrys diversification.
