Does Aronia or Hermannia have more species?
Aronia Aronia is a genus of deciduous shrubs, the chokeberries, in the family Rosaceae native to eastern North America and most commonly found in wet woods and swamps. The genus is usually considered to contain two or three species, one of which is naturalized in Europe. A fourth form that has long been cultivated under the name "Aronia" is now considered to be an intergeneric hybrid, "Sorbaronia mitschurinii".
Araceae The Araceae are a family of monocotyledonous flowering plants in which flowers are borne on a type of inflorescence called a spadix. The spadix is usually accompanied by, and sometimes partially enclosed in, a spathe or leaf-like bract. Also known as the arum family, members are often colloquially known as aroids. This family of 114 genera and about 3750 known species is most diverse in the New World tropics, although also distributed in the Old World tropics and northern temperate regions.
