What is "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.

In China, the species is called "mugua", while in Korea, it is called "mogwa" (hangul: 모과; Chinese/hanja: - not to be confused with "papaya", whose Chinese transliteration is also called ) which is used for medicine or for making beverages, such as mogwacha. In Japan, it is known as "karin - 花梨" (literally, "flowering pear").

It grows to 10–18 m tall, with a dense, twiggy crown. The leaves are alternately arranged, simple, 6–12 cm long and 3–6 cm broad, and have a serrated margin. The flowers are 2.5–4 cm diameter, with five pale pink petals; flowering is in mid spring. The fruit is a large ovoid pome 12–17 cm long with five carpels; it gives off an intense, sweet smell and it ripens in late autumn.
