Boechera missouriensis

A plant with a sporadic distribution across the eastern U.S., most abundant in the Ozark and Ouachita Mountains of Missouri and Arkansas. Large plants are very easily distinguished from Boechera laevigata by their strongly pinnatifid leaves, but in smaller plants this is less obvious and one must instead rely on the glabrous leaves and pedicels strongly ascending in fruit on B. missouriensis. In Indiana this species is known from the northeastern corner of the state.
