What are the morphological characteristics of this plant?

Thalictrum simplex has slender, erect stems that typically reach heights of 10 to 50 centimeters and bear small, inconspicuous flowers arranged in loose, terminal panicles. The leaves are divided into multiple narrow, linear segments that give the foliage a delicate, feathery appearance. These plants often exhibit a rhizomatous growth habit, allowing them to form small colonies in moist alpine or subalpine environments. The flowers are characterized by a lack of large petals, instead featuring small, yellowish or greenish sepals. Small, dry fruits known as achenes develop following pollination to facilitate seed dispersal.
