Which kind of plant is native to more locations, Chelidonium or Kirengeshoma?
Chelidonium Chelidonium majus, commonly known as greater celandine or tetterwort,(although tetterwort also refers to "Sanguinaria canadensis"), nipplewort, or swallowwort, is a herbaceous perennial plant, the only species in the genus Chelidonium. It is native to Europe and western Asia and introduced widely in North America.
Cyrtomium Cyrtomium is a genus of about 15-20 species of ferns in the family Dryopteridaceae, native to Asia, Africa (including Madagascar), and the Pacific Ocean islands (Hawaii). It is very closely related to the genus "Polystichum", with recent research suggesting it should be included within it (Little & Barrington).
