It is an annual herb growing up to 50 or 60 centimeters tall. The leaves are wavy-edged or lobed, the basal ones up to 5 centimeters long and ephemeral, and the upper ones with bases clasping the stem. The inflorescence is a long, open raceme of small whitish or purplish flowers. The fruit is a flattened, rounded, disclike capsule which hangs from its pedicel. It measures up to a centimeter long and is hairless to quite hairy in texture. The flat wing lining the edge of the disc is ribbed with rays like the spokes of a wheel, a characteristic making it easily distinguished from other Thysanocarpus when it is in fruit.
