The first true leaves are divided into three lobes. Leaves on mature plants are finely dissected and are arranged along the stem on short stalks. The foliage is covered with soft hairs. Fruit consists of one flat seed with short hairs on both faces. Flower heads are small and yellow and borne on stalks. Leaves of the flowering heads are brown at the tips. There are no prominent petals.
