Substratum: soil.Place: Bovec basin; next to the road from Bovec to Vri pass, about 500 m before Kal-Koritnica village, East Julian Alps, Posoje, Slovenia EC. Comment: Neotinea x dietrichiana is a small but beautiful natural hybrid between Three-Toothed Orchid Neotinea tridentata and Burnt-Tip Orchid Neotinea ustulata. Both species pose difficulties to taxonomy. They were originally placed to Neotinia genus, then transferred to Orchis genus and nowadays they landed in Neotinea genus. Orchids (Orchidaceae) often form hybrids among themselves, also among different genera. About 120 different combinations of natural crosspollination have been described in literature (Ref.5) resulting in different natural hybrids. But for Burnt-Tip Orchid Neotinea ustulata it is know that it was never found to have hybridized with any species other than Three-Toothed Orchid O. tridentata. These hybrids have been found several times in Slovenia; however this find is apparently the first in Upper Posoje region (northwest Slovenia).Protected according to: Uredba o zavarovanih prostoiveih rastlinskih vrstah, poglavje A, Uradni list RS, t. 46/2004 (Regulation of protected wild plants, chapter A, Official Gazette of Republic Slovenia, no. 46/2004), (2004).Pravilnik o uvrstitvi ogroenih rastlinskih in ivalskih vrst v rdei seznam, Uradni list RS, t. 82/2002 (Regulation of enlisting of endangered plant and animal species onto Red List, Official Gazette of Republic Slovenia, no. 82/2002) (2002). Indirectly enlisted in the Slovene Red List of rare and endangered species, marked by "V" representing a vulnerable species. The hybrid is not listed directly, but both its parents are.Ref.:(1) Conf. by Dr. Igor Dakskobler and Branko Dolinar.(2)
