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.
Physochlaina Physochlaina is a small genus of herbaceous perennial plants belonging to the nightshade family, Solanaceae, found principally in the north-western provinces of China (and regions adjoining these in the Himalaya and Central Asia) although one species occurs in Western Asia, while another is found as far east as those regions of Siberia abutting the eastern borders of Mongolia and also not only in Mongolia itself, but also the Chinese autonomous region of Inner Mongolia. The genus is a valuable one, since its species are not only of considerable medicinal value, being rich in tropane alkaloids, but also of ornamental value, three species having been grown for the purpose, although hitherto infrequently outside botanical gardens. Furthermore, the genus contains a species ("P. physaloides" - recorded in older literature under the synonyms "Hyoscyamus physaloides" and "Scopolia physaloides") formerly used as an entheogen in Siberia.
