Other info. - This striking little species can be found throughout much of Missouri but is most common in the Southeastern half of the state. The plant is easy to identify in flower because of its small size and purplish flowers. Another species, L. loeselii (L.) Rich., is similar but has smaller flowers with a yellow-green lip. This latter species is much less common in Missouri and is only found in a handful of Ozark counties.
