Richt. (Orchidaceae), a newly identified hybrid in Slovenian flora| Epipactis × schmalhausenii K. Richt. (Orchidaceae), novo opisani križanec v slovenski flori|This study analyzes nine specimens of the genus Epipac-tis from the Orchidaceae family and classifies them as Epipac-tis × schmalhausenii K. Richt (Epipactis atrorubens (Hoffm. ex Bernh.) Besser × Epipactis helleborine (L.) Crantz). The work provides the first detailed description of this hybrid in Slovenia. The plants were examined using the hybrid index (HI) method. We analyzed six to ten morphological plant characteristics. In addition to the traits summarized from the literature, two new characteristics related to the proportions of the flower labellum were analyzed from digital photographs and included in the study. Both of these showed high discriminatory power between the parental species. We modified the classical definition of the HI to no longer depend on the number of traits used in the analysis. The adopted trait descriptions of typical parental species were compared to six standard works on Orchidaceae. We did not observe any apparent contradictions, but the descriptions of some characteristics are somewhat inconsistent, which probably indicates their very high intraspecies variability. A brief assessment of potential geographical, site-related, and temporal barriers to hybridization between the two parental species in Slovenia revealed that none exist. The hybrid is likely quite common in Slovenia and has been overlooked until now, probably due to its substantial phenotypic diversityMorfološko opisujemo devet primerkov orhidej iz rodu Epipactis Zinn, ki smo jih prepoznali kot križance Epipactis × schmalhausenii K.

Rastline smo obravnavali z metodo indeksa hibridnosti (HI) na osnovi šestih do desetih morfoloških lastnosti povzetih po literaturi. V analizo smo dodali dve novi lastnosti, vezani na proporce medene ustne cvetov. Obe sta izkazali veliko diskriminatorno moč med obema staršema. Določevali smo jih iz digitalnih fotografij cvetov. Klasično definicijo HI smo preoblikovali tako, da rezultat ni več odvisen od števila opazovanih lastnosti in omogoča primerjavo križancev, ki so bili določeni na osnovi različnega števila opazovanih lastnosti. Privzete opise tipičnih lastnosti staršev smo primerjali z opisi v šestih standardnih literaturnih virih za družino Orchidaceae. Očitnih nasprotij nismo opazili, vendar so opisi nekaterih lastnosti nekoliko neenotni, kar verjetno kaže na njihovo veliko variabilnost. Kratka analiza morebitnih geografskih, rastiščnih in časovnih preprek za križanje je pokazala, da jih v Sloveniji ni. Križanec je v Sloveniji zato verjetno relativno pogost in je bil le zaradi velike fenotipske raznolikosti do zdaj bržkone spregledanTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaSlovenska akademija znanosti in umetnosti (SAZU)
