resembles the less widespread rorippa alpina
, and is found in similar habitats, but is a generally larger plant, with longer leaves and more upright stems. Plants produce one or several stems, usually held up at a low angle, less often running along the ground. The lower portions of the stems are lightly hairy, otherwise they are usually hairless, as are the leaves. Basal leaves are pinnately lobed, while stem leaves are lined by smaller lobes, or teeth; those at the top of the stem tend to have entire edges. Stem leaves are clasping while basal leaves have short stalks.
The inflorescence is a compact cluster when in bud, elongating as the flowers open. Sepals are purplish while the petals are yellow, spatulate in shape, and short, around 0.07 inches. The sepals have a very sparse covering of short, white, bristly hairs. Fruits are short pods, around four times as long as wide, on stalks held at a wide angle.
