Physochlaina

Physochlaina is a small genus of herbaceous perennial flowering 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 others occur in Siberia, Mongolia and the Chinese autonomous region of Inner Mongolia. Some sources maintain that the widespread species P. physaloides is found also in Japan, but the species is not recorded as being native in one of the few English-language floras of the country. The genus has medicinal value, being rich in tropane alkaloids, and is also of ornamental value, three species having been grown for ornament, although hitherto infrequently outside botanical gardens. Furthermore, the genus contains a species (P. physaloides – recorded in older literature under the synonyms Hyoscyamus physalodes, Hyoscyamus physaloides and Scopolia physaloides) formerly used as an entheogen in Siberia (re. which see translation of Gmelin's account of such use below).
