This species has a fibrous root system along an erect, green stem that is pubescent and contains short-stalked glands. The stems are also solitary and may be branched from the mid-stem. Basal leaves are often purple in color, oblanceolate, and unlobed with flat margins. Cauline leaves range from linear to linear-lanceolate with 3-5 lobes. Flowers are attached at the base by a large, green bract. They are bright yellow towards the apex. Each flower contains four sepals that form a yellow tube at the tip and white or light green at the base. The corolla contains five yellow-green petals which form a tube. The fruit is a capsule containing many small seeds. [3]
