What are the morphological characteristics of this plant?

Thalictrum petaloideuum has deeply lobed, trifoliate leaves with ovate or lanceolate leaflets that exhibit serrated margins and a distinctively delicate texture. The plant produces small, inconspicuous flowers that are surrounded by petal-like sepals, which give the inflorescence its characteristic appearance. These sepals are typically pale yellow or cream-colored and serve to attract pollinators in lieu of true petals. The stems are slender and often slightly branched, supporting the airy clusters of blooms. The root system consists of a rhizomatous structure that allows the plant to spread slowly through its woodland habitat.
