Neottia cordata

Neottia cordata, the lesser twayblade or heartleaf twayblade, is an orchid of upland bogs and mires. 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.

It is never very common but may be frequently overlooked because of its small size and a tendency to grow underneath heather on sphagnum moss.
