Do the Trailing bellflower and the Pseudocydonia sinensis belong to the same plant family?
Pseudocydonia Pseudocydonia sinensis, the Chinese quince, is a deciduous or semi-evergreen tree in the family Rosaceae, native to eastern Asia in China, and the sole species in the genus Pseudocydonia. It is closely related to the east Asian genus "Chaenomeles", and is sometimes placed in "Chaenomeles" as "C. sinensis", but notable differences are the lack of thorns, and that the flowers are produced singly, not in clusters. The Chinese quince is also closely related to the European Quince genus "Cydonia"; notable differences include the serrated leaves, and lack of fuzz.
Adenia Adenia is a genus of flowering plants in the passionflower family, Passifloraceae. It is distributed in the Old World tropics and subtropics. The centers of diversity are in Madagascar, eastern and western tropical Africa, and Southeast Asia. The genus name "Adenia" comes from "aden", reported as the Arabic name for the plant by Peter Forsskål, the author of the genus.
