Description: The flowers are in short racemes that are often below the leaves. The individual flowers are small, about 1/2 inch (1 cm) wide, non-fragrant, and have 4 narrowly egg-shaped petals with smooth, non-rippled margins. The flowers are followed by long, slender, woolly siliques (seed capsules) that are tipped with 2 horns that together look like a dolphin's tail. The leaves are green, woolly-haired above and below, basal and alternate, coarsely toothed or pinnately lobed, and oblanceolate in shape. The stems are green, leafy, mostly erect, and covered in woolly hairs.
The similar Night Scented Stock (Matthiola longipetala) is a larger plant with taller flower stalks and much larger, fragrant flowers with rippled petals, while Slimleaf Plainsmustard (Schoenocrambe linearifolia) has larger flowers with spoon-shaped petals, narrow, non-toothed, non-lobed leaves, and non-horned seed capsules, and Crossflower (Chorispora tenella) has strange-smelling, glandular-hairy foliage and non-horned seed capsules.
