Broad-lipped twayblade
Neottia convallarioides
''Neottia convallarioides'' is a species of orchid known by the common names broad-lipped twayblade and broad-leaved twayblade. 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, and all species of ''Listera'' have been moved to ''Neottia''.
''Neottia convallarioides'' is native to much of Canada and in parts of the United States . I also reportedly occurs in St. Pierre & Miquelon and on the Komandor Islands in the Bering Sea, part of the Russian Far East.
''Neottia convallarioides'' is a plant of cool, moist, dim habitat, such as woods and forest, as well as swamps and streambanks. It is a rhizomatous perennial herb growing erect 10 to 35 centimeters tall. It has one pair of green oval leaves each up to 7 centimeters long near the base of the stem. The inflorescence is a small raceme of green or yellow-green flowers, sometimes slightly purple-tinged. Each has usually 3 reflexed lance-shaped sepals, 2 similar petals, and one petal known as the lip, which is longer, wedge-shaped, and notched at the tip. The plant sometimes forms large colonies, creating a groundcover. It is known to hybridize with ''Neottia auriculata''.
