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.
