A family of about 8 genera and 80 species, mostly temperate and northern hemisphere, but extending into South America (Peru). We here accept a narrower circumscription of Melanthiaceae (excluding Trilliaceae, Xerophyllaceae, Chionographidaceae, and Heloniadaceae) than currently traditional, based on the age, phylogeny, and morphological distinctiveness of the units (Kim, Kim, & Kim 2019).
