[Wikipedia] Etymology, Description, Ecology: Neottia cordata, the lesser twayblade[2] or heartleaf twayblade,[3] is an orchid of upland bogs and mires that rarely exceeds 15 cm (5.9 in) 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.[4] 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. Ecology The flowers produce nectar and are pollinated principally by fungus gnats in the groups Mycetophilidae and Sciaridae.[7] Mycorrhizal partners are almost exclusively fungi in the Sebacinales clade Serendipitaceae. There may also be some association with Ceratobasidiaceae and/or Tulasnellaceae.[7][8] (contributed by Mary Ann Machi)
