Plitvice Lakes (Plitvicka-Jezera National Park), Croatia (June, 2016).
Former Listera, now Neottia ovata.
We saw this one growing under a wooded path going through the woods of Plitvice. The flowering stems are typically 20–60 cm. the number of flowers varies from 15 to a bit less than 100. The flowers are small and yellowish-green in colour. The sepals and the two side petals form a fairly open hood; the labellum or lip is long and divided at the end into two lobes.
''Neottia ovata'' is a terrestrial orchid widespread across much of Europe, including the British Isles, as well as Siberia, Central Asia, Southwest Asia and the Himalayas. It has been introduced into Ontario, Canada, where it has been called the Eggleaf Twayblade. It was formerly placed in the genus ''Listera'', but molecular phylogenetic studies have shown that ''Neottia nidus-avis'', the Bird's-nest Orchid, evolved within the same group, and the two genera have been combined.
