Notes.
Menisdaurin is the sole non-BIA compound. Phylogenetically, Enemion and Isopyrum cluster together, which is closer to Dichocarpum than to Aquilegia; Thalictrum is closer to Leptopyrum and Paraquilegia than to the above four genera. All these genera belong to the subfamily Thalictroideae of Ranunculaceae.
