Thalictrum ramosum B. Boivin

This species is similar to Thalictrum fortunei, but differs in having small sepals and many narrowly ovoid achenes; it is also similar to T. javanicum, which differs in being taller and having inflorescences much branched and many flowered, sepals long, and filaments broader than anthers.

Thalictrum ramosum is used medicinally.

Inflorescence monochasial. Pedicel filiform, 5--10 mm. Sepals 4, early deciduous, white, tinged purplish, ovate, ca. 2 mm.
