Thalictrum Linnaeus. Subfamily: Thalictroideae. Meadow-rue.

Key to Thalictrum

A genus of about 330 species, perennial herbs, of Eurasia, North America, South America, and Africa. Ro & McPheron (1997) corroborated via molecular phylogeny that Anemonella should be included in Thalictrum; in fact, T. thalictroides appears to form a "basal" subclade in Thalictrum with T. clavatum (and presumably T. mirabile).

ID notes: Thalictrum thalictroides is superficially similar to Enemion biternatum, but can be distinguished by the following characters: fruit an achene (vs. fruit a follicle), petaloid sepals 5-10 (vs. 5).
