Borodinia missouriensis, commonly called Missouri rockcress,[1][2] is a species of flowering plant in the mustard family (Brassicaceae). It is native to the eastern United States, where it has a highly fragmented range localized in the Northeast, the Upper Midwest, the Interior Highlands, and the Southeast.[3][4] Its natural habitat is typically on rocky or sandy woodlands and bluffs, in areas of acidic soil.[5][2] It is generally uncommon throughout most of its range, with exception for the Interior Highlands region.[6]

Borodinia missouriensis is an erect biennial. It produces racemes of small creamy-white flowers in the spring.[7][5] It bears a resemblance to more widespread Borodinia laevigata, from which it can be distinguished by the following characters: Stem leaves dense, erect, and overlapping, basal leaves persistent and pinnately lobed, petals about twice as long as sepals, and stems often red-tinged.[5][1]
