Plant Genera


Family Code: RANUNC
Genus Code: ENEMI
Genus CN: false rue anemone
Genus Authority: Raf.
Genus Summary: A genus of about 6 species, perennial herbs, of temperate North America and e. Asia. The issue of the separation of the genus Enemion from Isopyrum remains somewhat controversial; I here follow Keener (1977), Tamura (1993), and Ford (1997).
Genus Identification: Identification notes: Enemion is somewhat superficially similar to the more common and widespread (in the Flora area) Thalictrum thalictroides, with which it also sometimes grows, but can be distinguished by the following characters: stem leaves 1-4 and alternate (vs. stem leaves 2 and opposite), fruit an aggregate of follicles (vs. fruit an aggregate of achenes), petaloid sepals 5 (vs. 5-10, usually some at least of the flowers on a plant with 6 or more), leaflets deeply lobed, at least some of the leaflets on a plant with sinuses at least 1/3 as long as the leaflet (vs. leaflets shallowly lobed, the notches < 2 mm long).
Genus References: Ford in FNA (1997); Tamura in Kubitzki, Rohwer, & Bittrich (1993); Keener (1977).
