Neottia auriculata (syn. Listera auriculata), the auricled twayblade,[2] is a species of terrestrial orchid found in northeastern North America (Labrador, New Brunswick and Maine west to Manitoba and Minnesota.[1][3][4]

Description

N. auriculata when mature, has two ovate, sessile leaves that are paired on the stem but arranged oppositely.[5] It has small pale-green flowers with three sepals and three petals, the lowest petal is modified into a wider lip - which is divided from one-fourth to one-third its length.[5]

Distribution and habitat

N. auriculata is a rare orchid species, which was in 1975 proposed as a threatened species in the US, but subsequent surveys found that it existed in greater abundance than initially thought.[5] In the Great lakes region it occupies a very specific habitat, which has sandy soils just about the high water line of rivers that enter lake Superior. It is associated with alders or mossy-banks under trees.[5]
