Appearance
The flowering stems are typically 20–60 cm tall, occasionally up to 75 cm. There are two large opposite basal leaves, 5–20 cm long. A variable number of flowers is borne on the stems, usually more than 15 but less than 100. The flowers are small and yellowish-green in colour. The sepals and the two side petals form a fairly open hood, 5–6 mm long; the labellum or lip is 7–15 mm long and is divided at the end into two lobes.
Naming
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.
Habitat
"Neottia ovata" grows in a variety of habitats: woods, meadows, dune-slacks and moorland.References:
