Oxypolis Rafinesque. Common name: Dropwort, Hog-fennel, Cowbane.
A genus of about 4 species, perennial herbs, of temperate North America (Plunkett et al. 2018a). Based on work of Feist et al. (2012) and Feist & Downie (2008), Oxypolis has been limited to the species with compound leaves, distributed in eastern and w. North America. The compound-leaved Oxypolis form a clade far-removed within tribe Oenantheae from the quill-leaved Oxypolis and Ptilmnium and compound-leaved Ptilimnium. The 3 taxa of Oxypolis with “quill- or “rachis-leaves” are placed in Tiedemannia, endemic to se. United States and the West Indies.
