Are Hellebore and Aethionema from the same flowering plant families?
Hellebore Commonly known as hellebores , the Eurasian genus Helleborus consists of approximately 20 species of herbaceous or evergreen perennial flowering plants in the family Ranunculaceae, within which it gave its name to the tribe of Helleboreae. The scientific name "Helleborus" derives from the Greek name for "H. orientalis", ἑλλέβορος "helléboros", from "elein" "to injure" and βορά "borá" "food". Many species are poisonous. Despite names such as "winter rose", "Christmas rose" and "Lenten rose", hellebores are not closely related to the rose family (Rosaceae).
Madieae Madieae is a tribe of flowering plants in the sunflower family, Asteraceae. It is sometimes considered a subtribe of Heliantheae. Notable species include the tarweeds of the Western United States as well as the silverswords of Hawaii.
