The leaves are mostly found at the base of the plant and may either have leaves on the stems or they may be absent.<ref name="4Corners" /> The basal leaves are attached to the plant by short stems and range in length from just 0.3&nbsp;centimeters to as much as 3.5&nbsp;cm. The surfaces of the leaves are also usually pubescent.<ref name="FNA" /> Plants usually have one to three cauline leaves directly attached to the stems (sessile), but may occasionally lack them or have as many as five.<ref name="4Corners" />

The stem bears an inflorescence with two to thirty small yellow flowers.<ref name="4Corners" /> The fruit is a silique, a type of narrow pod made up of two fused carpels, most often ranging in length from 6–12&nbsp;millimeters, but occasionally as short as short as 4&nbsp;mm or as long as 15&nbsp;mm.<ref name="4Corners" /><ref name="FNA" />
