Lepidium is also known as Lepidium with glandular stems, spicy vegetables, hemp vegetables, and urinary vegetables. It is an annual or perennial herbaceous plant of the Brassicaceae family, with a plant height of 5 to 30 cm, a white main root, and a spicy taste when young. The stem is upright, with many branches at the base and a capitate gland head. Basal leaves are clustered, with long stalks, narrow spatulate leaves, pinnately lobed or deeply lobed; stem leaves are alternate, sessile, strip-shaped, sparsely toothed or entire. The racemes are terminal, the flowers are very small, and the sepals fall early; the petals degenerate into filaments. The short siliques are nearly round or oval, flat, with an emarginate apex and extremely narrow wings on the upper part. Seeds are obovate, oval, brownish red. Propagation by seeds.

Lepidium is a common weed in wheat and vegetable fields, and wheat is severely affected.
