Erysimum inconspicuum inhabits a wide range of habitats, elevations and locations. The reddish stems grow vertically upwards, branch (if at all) towards the top, and have bear relatively few leaves, around the base and along the stem. Leaves are long and narrow, sometimes slightly curved up along the axis, and covered by short, appressed, branched hairs; divided into two or three. Margins may be entire or fine toothed. Leaf tips are pointed. Cauline leaves are angled upwards, close to the stem. Basal leaves tend to be withered at flowering time.
Flowers are formed of four oblong, reddish-yellow sepals, the opposite pairs slightly different in shape, and four clawed, oblanceolate, yellow petals, approximately equal in length - around a third of an inch. Petal tips are rounded. Fruits are ascending, narrow, straight and linear, up to 2.5 inches long.
