The unique bond between the Ophrys speculum orchid and the male Dasyscolia ciliata wasp primarily stems from a few distinctive semiochemicals that mimic the female wasp\u2019s sex pheromone, although the floral scent comprises a variety of compounds. An osmophore producing highly volatile compounds has been documented in four close relatives of O. speculum and is now being also investigated in this species. Given the existing debates regarding the structure of the labellum and stigmatic cavity in O. speculum, this study details their micromorphology. Additionally, comparisons of O. speculum flowers and female D. ciliata wasps under stereomicroscopy and scanning electron microscopy are conducted to seek new evidence of visual and tactile mimicry. The findings confirm that (i) an osmophore is present at the apical margin of the labellum in O. speculum flowers; (ii) the labellum features a distinct basal field homologous to those found in other Ophrys species; and (iii) the basal labellum region closely mimics the female wasp\u2019s thorax and wings. The implications of these novel floral features are discussed within an evolutionary context.<\/jats:p>","DOI":"10.3390\/plants13101413","type":"journal-article","created":{"date-parts":[[2024,5,20]],"date-time":"2024-05-20T03:36:42Z","timestamp":1716176202000},"page":"1413","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Osmophore Structure and Labellum Micromorphology in Ophrys speculum (Orchidaceae): New Interpretations of Floral Features and Implications for a Specific Sexually Deceptive Pollination Interaction"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4570-7424","authenticated-orcid":false,"given":"Ana","family":"Francisco","sequence":"first","affiliation":[{"name":"Centro de Estudos do Ambiente e do Mar (CESAM Lisboa), Faculdade de Ci\u00eancias da Universidade de Lisboa (FCUL), C2, Campo Grande, 1749-016 Lisboa, Portugal"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7439-5912","authenticated-orcid":false,"given":"Lia","family":"Ascens\u00e3o","sequence":"additional","affiliation":[{"name":"Centro de Estudos do Ambiente e do Mar (CESAM Lisboa), Faculdade de Ci\u00eancias da Universidade de Lisboa (FCUL), C2, Campo Grande, 1749-016 Lisboa, Portugal"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,5,18]]},"reference":[{"key":"ref_1","unstructured":"van der Pijl, L., and Dodson, C.H.
