Claim: Stephanodoria are classified in the plantae clade under the Asterales order, which are an order of dicotyledonous flowering plants which is a cosmopolite .
Evidence: A clade (/kleɪd/; from Ancient Greek: κλάδος, klados, "branch"), also known as a monophyletic group or natural group, is a group of organisms that are monophyletic—that is, composed of a common ancestor and all its lineal descendants. Some recent classifications based on modern cladistics have explicitly abandoned the term "kingdom", noting that the traditional kingdoms are not monophyletic, i.e., do not consist of all the descendants of a common ancestor. The common ancestor may be an individual, a population, a species (extinct or extant), and so on right up to a kingdom and further. Kingdom: Plantae Order: Asterales Asterales /æstəˈreɪliːz/ is an order of dicotyledonous flowering plants that includes the large family Asteraceae (or Compositae) known for composite flowers made of florets, and ten families related to the Asteraceae. The order is a cosmopolite (plants found throughout most of the world including desert and frigid zones), and includes mostly herbaceous species, although a small number of trees (such as the giant Lobelia and the giant Senecio) and shrubs are also present.
