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,{{Citation |last=Stace |first=Clive |authorlink = Clive Stace |year=2010 |title=New Flora of the British Isles |edition=3rd |location=Cambridge, UK |publisher=Cambridge University Press |isbn=978-0-521-70772-5 }}, p. 864 and all species of Listera have been moved to Neottia.{{Citation |contribution=Listera|title=World Checklist of Selected Plant Families |publisher=Royal Botanic Gardens, Kew |url=http://apps.kew.org/wcsp/namedetail.do?name_id=114075 |accessdate=2012-04-04 }}
Description
It is a rhizomatous perennial herb growing 10 to 35 centimeters tall. It has one pair of green oval leaves 2 to 7 cm long near the base of the stem. The inflorescence is a small raceme of green or yellow-green flowers. Each has 3 reflexed lance-shaped sepals, 2 similar petals, and a lobed, wedge-shaped labellum that measures 9 to 13 mm long. The plant sometimes forms large colonies, creating a groundcover.Hoy, J. (2002).

Distribution and habitat
Neottia convallarioides can be found in moist habitats such as woods, forests, swamps, and streambanks. It is native to much of Canada and in parts of the United States (Alaska, the Great Lakes Region, New England, and the mountains of the West: Rockies, Cascades, Sierra Nevada, etc.). It also reportedly occurs in St. Pierre & Miquelon and on the Komandor Islands in the Bering Sea, part of the Russian Far East.[http://www.efloras.org/florataxon.aspx?flora_id=1&taxon_id=242101754 Flora of North America v 26 p 590, Broad-leaved twayblade, Listera convallarioides (Swartz) Nuttall ex Elliott, Sketch Bot.
