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".
Begonia masoniana Begonia masoniana, the iron cross begonia, is a species of plant in the family Begoniaceae, native to New Guinea. It is a rhizomatous perennial begonia growing to 0.5 m , bearing large, asymmetrical, textured green leaves covered in reddish hairs, with a prominent dark brown pattern in the centre of each leaf, reminiscent of the German Iron Cross. It produces small white flowers in erect panicles, but is cultivated mainly for its foliage effect. In temperate regions it must be grown under glass, or in a completely frost-free environment.
