About Borodinia missouriensis (Greene) P.J.Alexander & Windham
Borodinia missouriensis, commonly known as Missouri rockcress, is a flowering plant species belonging to the mustard family (Brassicaceae). It is native to the eastern United States, where it has a highly fragmented distribution. Local populations of this species occur in the Northeast, Upper Midwest, Interior Highlands, and Southeast regions of the country. Its natural habitat is most often found on rocky or sandy woodlands and bluffs that have acidic soil. It is generally uncommon across most of its range, except in the Interior Highlands region. Borodinia missouriensis is an erect biennial plant. In spring, it produces racemes of small creamy-white flowers. It looks similar to the more widespread species Borodinia laevigata, but can be told apart by several distinct features: its stem leaves are dense, erect, and overlapping; its basal leaves are persistent and pinnately lobed; its petals are roughly twice as long as its sepals; and its stems are often red-tinged.
