Series: European Terrestrial Orchids

Nigritella austriaca (syn: Nigritella nigra subsp. austriaca ; Gymnadenia austriaca) (NL: "Oostenrijkse Vanilleorchis" / EN: ? / DE: Österreichisches Kohlröschen (Schwärzlein, Brändele, Brunelle, Blutrösli, Blutströpfli, Mohrenköpfli, Schokoladenblümli, Vanilleblümli) / FR: Nigritelle d'Autriche) is a species of European terrestrial Orchid. In the Italian Dolomites two "black" Nigritella's can be found: N. rhellicani (see image posted on 16 aug 2011) and N. austriaca (this image). The two are very similar in appearance, so a realy close look is needed for proper determination. The plant height of both species is 15 (10-20 cm). The flowers of N.austriaca are a little brighter and therefore slightly more reddish. The inflorescence is shorter than N.rhellicani, hemispherical to spherical flourished, rather broader than high. Typically is the the strong scent of chocolate / vanilla. The flowers are also slightly larger (lip: 7,5-9,6 mm) than those of N. rhellicani (lip: 5-7 mm). A good magnifying glass is needed to make the difference at the edge of the lower bracts visible: In N. rhellicani this often carries a seam of 0.05-0.1 mm long papillae while on N. austriaca the edge is smooth or bumpy, filled with more than a few very short papillae. N.austriaca blooms at the same location approximately 8-10 days before N.Rhellicani. N. austriaca is tetraploid (2n = 80) and has an apomictic reproduction.
