Other info. - Missouri has no recognized endemic species, but this plant is close. It is found only in Missouri's Ozarks and in the Ouachita mountains of Arkansas. It is easily recognized by its symmetrical, 3-parted purple or pink flowers, strap-like leaves, and the virtual absence of a stem. The flowers are borne down among the leaf bases instead of above the leaves on a long stalk, as with most other species in the genus. The flower stalks and sepals are glandular.
