N. auriculata when mature, has two ovate, sessile leaves that are paired on the stem but arranged oppositely. 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.{{cite book|author1=Barbara Coffin|author2=Lee Pfannmuller|title=Minnesota's Endangered Flora and Fauna|url=https://books.google.com/books?id=wfWNq91AjeoC|year=1988|publisher=U of Minnesota Press|isbn=978-0-8166-1689-3|page=107}}
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. 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.
