Treated historically in our floras as Habenaria hyperborea (which has since been synonymized under Platanthera hyperborea (Linnaeus) Lindley). The North American plants have been split intos Platanthera aquilonis and Platanthera huronensis. The North American species is apparently diploid compared to the tetraploid P. hyberborea. The differences between "aquilonis" and "huronensis" are somewhat arcane and without flowers or seeing plants here previously in flower, an ID might not be possible. The leaves and congested inflorescence might suggest "huronensis" but that would still be wrong.Yet: this is neither. Most likely this is Platanthera tescamnis.August 18, 2007, Red Butte Canyon, Salt Lake County, Utah

Platanthera bifolia ssp. bifolia (L.) Rich., syn.: Orchis bifolia L.Lesser Butterfly-orchid, DE: Weie Waldhyazinthe, Zweiblttriges BreitklbchenSlo.: dvolistni vimenjakDat.: May 25. 2015Lat.: 46.40111 Long.: 13.70527Code: Bot_878/2015_DSC6825Habitat: grassland, pasture, locally flat terrain; alluvial, skeletal, calcareous ground; shallow soil layer, sunny, open place; exposed to direct rain; elevation 980 m (3.200 feet); average precipitations ~ 3.000 mm/year, average temperature 4-6 deg C, alpine phytogeographical region. Place: Zadnja Trenta valley, Zapodn place, right bank of dry riverbed of Soa, East Julian Alps, Posoje, Slovenia EC.Comment: A single plant found still in buds. It was growing among Primula farinosa and Convalaria majalis, which signifies quite humid ground in spite of pure calcareous alluvium. Fully open and sunny habitat is also to some extent unusual for Platanthera bifolia ssp. bifolia.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).According to 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) enlisted in the Slovene Red List of rare and endangered species, marked by V representing a vulnerable species.Ref.:(1) H.Baumann, S.

Platantera chlorantha (Cust.) Rchb. right side; Platanthera bifolia left. sideGreater Butterfly-orchid, DE: Grnliche Breitklbchen Slo.: zelenkasti vimenjakDat.: June 10. 2008Lat.: 45.94698 Long.: 14.14335Code: Bot_Bot_270/2008_DSC9355Habitat: shallow valley, light mixed wood with dense grassy ground vegetation, half shade, humid place, almost flat terrain, partly protected from direct rain by tree canopies, average precipitations 1.800-2.000 mm/year, average temperature 7-9 deg C, elevation 570 m (1.900 feet), prealpine phytogeographical region. Substratum: soil.Place: ejna dolina (Thirsty valley) near Hotedrica village, Notranjska, Slovenia EC. Protected according to 'Uredba o zavarovanih prostoiveih rastlinskih vrstah'Url. RS, t. 46/2004 (Regulation of protection of wild growing plants, Official Gazette of Republic Slovenia, No.:46/2004). Enlisted in the Slovene Red List of rare and endangered species, marked by "V" representing a vulnerable species.Comment: Platanthera chlorantha is essentially a European orchid with very few disjunct locations in North Africa and Asia. In Slovenia it grows scattered, however, it is less common than it's closely related 'sister' Platathera bifolia (Lesser Butterfly-orchid). Both plants grow in the same habitats, are more or less whitish-greenish, have two or three large ground leaves and are fragrant and their habitus is also similar. It is not always easy to tell them apart in spite of several detailed differences. The most reliable distinguishing trait seems to be orientation and distance between pollinia. Platanthera chlorantha has pollinia widely separated and they lean in towards each other at the tops while Platantera bifolia has them close together and they are vertical and parallel (see Fig. 5, Platanthera chlorantha right, Platantera bifola left). The flowers have very long spurs. Not every insect can reach the nectar in them, they have to have very long proboscis. The main pollinators are moths, which are attracted mainly by flowers' smell. Interestingly, widely separated pollinia of Platanthera chlorantha stick their pollen to moths' eyes when they try to protrude with their heads deep into the long spur. Apparently for orientation smell is more important to them than sight?Ref.:(1) A. Martini et all., Mala Flora Slovenije, Tehnina Zaloba Slovenije (1999) (in Slovene), p 998. (2)

Platanthera bifolia ssp. bifolia (L.) Rich., syn.: Orchis bifolia L.Lesser Butterfly-orchid, DE: Weie Waldhyazinthe, Zweiblttriges BreitklbchenSlo.: dvolistni vimenjakDat.: June 18. 2015Lat.: 46.36653 Long.: 13.72440Code: Bot_888/2015_IMG8334Picture file names: from Platanthera-bifolia-ssp-bifolia_raw_50 to Platanthera-bifolia-ssp-bifolia_raw_68.Habitat: light mixed forest, Picea abies, Fagus sylvatica dominant; moderately inclined mountain slope, northwest aspect; calcareous, colluvial, stony ground; quite humid place; mostly in half shade; mostly exposed to direct rain; elevation 565 m (1.850 feet); average precipitations ~ 3.000 mm/year, average temperature 7-9 deg C, alpine phytogeographical region. Place: Lower Trenta valley, left bank of river Soa between villages Trenta and Soa, downstream of farmhouse Maselc, East Julian Alps, Posoje, Slovenia EC.Comment: Platanthera bifolia ssp. bifolia is a beautiful, gracious and quite common wild orchid of Trenta valley. At the place of this observation there were more than hundred blooming plants present on a relative small place. The plant is a wide spread species and grows in the whole alpine belt and other European mountains including Pyrenees and Carpathians. It is very similar to his sister Greater Butterfly-orchid (Platanthera chlorantha), which has more greenish flowers but very similar habitus and sometimes builds hybrids with Platanthera bifolia ssp. bifolia, where they grow together. In such cases it is not always easy to determine properly plants found. The most reliable distinguishing trait of both species is position of their pollinia (see picture Platanthera-bifolia-plus-chlorantha_1). With Platanthera bifolia ssp. bifolia (left) they are parallel and close together. The entrance to spur is sometimes hard to see. Contrary, with Platanthera chlorantha (right) pollinia are divergent and widely separated. The entrance to spur is clearly visible. Both plants have unusually long and slender spur. Only certain night-flying moths have long enough proboscis to be able to reach nectar at the bottom of the long spur.Canon G11, 6.1-30mm/f2.8-4.5Protected 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).According to 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) enlisted in the Slovene Red List of rare and endangered species, marked by "V" representing a vulnerable species.Ref.:(1) H.Baumann, S.
