Volatile compounds were collected in the field from individual specimens of un‐pollinated and hand‐pollinated Platanthera bifolia , and investigated by combined gas chromatography‐mass spectrometry (GC‐MS). In all, 32 compounds were identified of which five were not previously reported in Platanthera. Pollinated flowers wilted significantly faster than unpollinated flowers. Twentyfour hours after pollination the production of volatile compounds had decreased slightly and there was a small change in their composition. Variation in floral scents within and between populations, as well as effects of changes in floral attractiveness on pollination and reproductive success are discussed.
