About Thelypodium laciniatum (Hook.) Endl.
Thelypodium laciniatum is a biennial herb that grows from a radish-like taproot. It produces many erect stems, which sometimes grow over one meter in height. The stems are hairless, solid, and often have a waxy texture. The thick green basal leaves have blades divided into multiple lance-shaped lobes or segments; leaves positioned higher on the plant are smaller and less divided. The large inflorescence is a dense, spikelike raceme of mustard-like flowers, which each have four sepals and four petals. Both sepals and petals are whitish or pale lavender, and the flowers bloom in early summer. The fruit is a narrow, cylindrical silique that can reach 10 to 14 centimeters in length. When the plant is in fruit, the raceme is covered in these siliques, which either curve or extend straight outward like whiskers.
