In the latest edition of the Berichte aus den Arbeitskreisen Heimische Orchideen (Jg 34, Heft 2, 2017, S.123-145), Norbert Griebl presents the diversity of alpine orchid hybrids on the meadows of the Golzentipp mountain (2317 m) in Eastern Tirol. Among them there is also a white-flowered hybrid of Gymnadenia conopsea and Nigritella rhellicani (Gymnigritella suaveolens). Griebl views two possible options:
- a white-flowered Nigritella rhellicani, which can be rarely found at the Golzentipp, and a white-flowered Gymnadenia conopsea, which is not rare in this region, have hybridized
- a spontaneous mutation of a hybrid affecting the production of color pigments.
Griebl sees a higher probability for the second case. This is supported by the fact that there have been no reports of such an Albiflora hybrid in other regions with color varieties of Nigritella rhellicani and white-flowered Gymnadenia conopsea, for example on the Seiser Alm in Southern Tirol – though these Suaveolens hybrids can be regularly seen there.
