What are the morphological characteristics of this plant?

Lepidium apetalum has an erect, perennial herb structure characterized by a woody base, slender stems, and small, ovate to lanceolate leaves that are often sparsely distributed. The foliage typically displays a grayish-green hue due to a fine coating of hairs on the surface. Its reproductive structures consist of small, inconspicuous white flowers arranged in dense terminal racemes. Following pollination, the plant produces tiny, flattened silicles that are characteristic of the Brassicaceae family. These seeds are contained within capsules that eventually disperse to facilitate new growth.
