Heartleaf twayblade (Neottia cordata)
Description
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. 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. The single erect flower-stem is often tinged red and is clasped near the base by a pair or ovate-orbicular glossy green leaves. The small flowers which look deceptively simple in structure for an orchid, are purple-green in colour with a somewhat swollen calyx.
