Neottia cordata

Template:Italic title Template:Taxobox

Neottia cordata (as Listera cordata) from Bilder ur Nordens Flora

Neottia cordata, lesser twayblade<ref name=BSBI07>Template:Cite web</ref> or heartleaf twayblade<ref>Template:PLANTS</ref> 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.<ref name=Stac10>Template:Citation, p. 864</ref>

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.

Distribution

It has a circumpolar distribution being found in Europe, Asia, Greenland and large parts of North America. In the United Kingdom its distribution is western and northern becoming most common in the western highlands and is also found in Snowdonia and the Lake District.<ref>Template:Cite web</ref> (Codes) <ref>Template:Cite web</ref>
