We describe the first reported intergeneric hybrid to naturally occur between two subspecies belonging to different genera, Dactylorhiza fuchsii subsp. sooana (genus Dactylorhiza) and Pseudorchis albida subsp. tricuspis (genus Pseudorchis), as x Pseudorhiza nieschalkii (Senghas) P.F.Hunt nothosubsp. siculorum H.Kertesz & N.Anghelescu, 2020. The hybrid was found and digitally photographed for the first time by Hajnalka Kertesz in June, 2020, within Terra Siculorum, in one of the Natura 2000 protected areas, known as Harghita Mădăraș, ROSCI00090. Following detailed morphometric analysis using 67 characters and molecular karyological analyses, we identified this unique specimen as an intergeneric hybrid, new to science. The hybrid, an F1 generation plant, most likely representing a single intergeneric pollination event, is phenotypically intermediate between its parental species in most of the characters scored, but it significantly closely resembles Pseudorchis albida subsp. tricuspis parent. Since the parental species occurred in near proximity (1-10 meters distance), we suggest that the production of this hybrid required a minimum travel distance of ca 1-10 meters, by the pollinators and frequent exchange of pollen between the parental species was very likely. The parental species and the hybrid, which display a considerable synchronicity in their flowering time, overlap in pollinator community, sharing various species of Hymenopterans and Dipterans, very abundant in the heathland. This Terra Siculorum hybrid is thus best described as a rarely occurring intergeneric hybrid that shows strong Pseudorchis albida subsp. tricuspis parental dominance in inheritance patterns.

×Pseudorhiza nieschalkii（Senghas）PFHunt nothosubsp。siculorumH.Kertész和N.Anghelescu，2020年在罗马尼亚特拉克拉科鲁姆发现新的跨代兰花杂种

我们描述了第一个报道的属间杂种，该杂种自然发生在属于不同属的两个亚种Factsor fuchsii亚种之间。sooana（Dactylorhiza属）和Pseudorchis albida亚种。Tricuspis（属Pseudorchis），如x Pseudorhiza nieschalkii（Senghas）PFHunt nothosubsp。siculorum H.Kertesz和N.Anghelescu，2020年。HajnalkaKertesz于2020年6月在Terra Siculorum的Natura 2000保护区之一，名为Harghita Mădăraș，ROSCI00090中首次发现并用数码照相。在使用67个字符进行了详细的形态分析并进行了分子动力学分析后，我们确定了这种独特的标本是一种跨学科杂种，这对科学来说是新的。杂种，F1代植物，很可能代表单个属间授粉事件，在大多数得分角色中，表型在其亲本物种之间处于表型中间，但与拟南芥假单胞菌非常相似。Tricuspis的父母。由于亲本物种发生在附近（距离为1-10米），我们建议这种杂交种的生产需要传粉媒介最小传播距离约为1-10米，并且亲本物种之间的花粉交换非常频繁。可能。在开花时间上显示出相当大的同步性的亲本物种和杂种在传粉媒介群落中重叠，共享在石南丛生地中非常丰富的膜翅目和Dipterans种。因此，这种Terra Siculorum杂种最好被描述为一种罕见的属间杂种，显示出强大的白假单胞菌亚种。
