What are the morphological characteristics of this plant?

Thalictrum viscosum has glandular-pubescent stems, compound leaves divided into three leaflets with coarsely toothed margins, and small yellowish-green flowers arranged in loose racemes. The sticky texture of the plant is caused by the presence of numerous glandular hairs covering much of its vegetative surface. Each leaf is typically ternately compound, featuring leaflets that are often lobed or irregularly shaped at the edges. The inflorescence consists of several small, inconspicuous flowers that lack showy petals, relying instead on sepals for visual structure. These botanical characteristics distinguish it from other members of the Ranunculaceae family.
