Neottia cordata, lesser twayblade or heartleaf twayblade is an orchid of upland bogs and mires that rarely exceeds 15 cm in height. 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.
