Comments: Yellow wide-lip orchid is also commonly called Loesel's twayblade. This species occurs in wetlands whereas the other native twayblad, Liparis liliifolia, is restricted to uplands. The latter is also self-incompatible, whereas the yellow wide-lip orchid is self-compatible. Only three species occur in the whole of North America north of Mexico with one restricted to Florida.
Yellow wide-lip orchid is on Indiana's state watch list.
Etymology: The genus, Liparis, is derived from the Greek word, liparos, meaning "oily" or "greasy". The specific epithet is derived from the German botanist, Johann Lösel.
