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.
Uvularia Uvularia is a genus of plants in the family Colchicaceae, close to the lily family (Liliaceae). They are commonly called bellworts, bellflowers or merrybells. The genus name is derived from the Latin "ūvula" meaning "little grape," likely because of the way the flowers hang downward. For the same reason "Uvularia" may also refer to the similarly derived palatine uvula, which hangs down from the soft palate in the mouth. This unusual flower is found in April and May, often on wooded slopes or in ravines and it spreads by stolons, or stoloniferous rhizomes. The plants are usually 18 to 24 inches (45–60 cm) in height and bear one or two flowers which hang downward from the axils of the leaves.
