Epipactis atrorubens (Hoffm. ex Bernh.) Besser - Orchidaceae
dark red helleborine, Braunrote Stendelwurz, Rot-Ständelwurz, Strandvanille
Orchid, up to 80cm tall, native to Europe; flowers reddish-brown to purple, emitting a wonderful vanilla-like and aromatic spicy scent. The flower scent also explains the German name 'Strandvanille' = 'beach vanilla' for plants growing on the islands of Rugia and Usedom at the coast of the Baltic sea. https://de.wikipedia.org/wiki/Braunrote_Stendelwurz
GC-MS analysis of nectar from examined Epipactis species (collected from flowers by using capillary glass with methylene chloride or n-pentane as eluents) showed compounds like 3,4-dimethoxybenzaldehyde (veratraldehyde), 1-methoxy-4-methyl benzene (para-methyl anisole), octanal, nonanal, and decanal.
E. atrorubens nectar also contained compounds not found in other species like 2-methoxy-4-methylphenol (4-methyl guaiacol) and 3,4-dimethoxytoluene (4-methylveratrole) e.g.
