The Quince (Cydonia oblonga) is the sole member of the genus Cydonia and native to warm-temperate southwest Asia in the Caucasus region. It is a small deciduous tree, growing 5-8 m tall and 4-6 m wide, related to apples and pears, and like them has a pome fruit, which is bright golden yellow when mature, pear-shaped, 7-12 cm long and 6-9 cm broad. The immature fruit is green, with dense grey-white pubescence which mostly (but not all) rubs off before maturity in late autumn when the fruit changes colour to yellow with hard flesh that is strongly perfumed. The leaves are alternately arranged, simple, 6-11 cm long, with an entire margin and densely pubescent with fine white hairs. The flowers, produced in spring after the leaves, are white or pink, 5 cm across, with five petals. Quince is used as a food plant by the larvae of some Lepidoptera species including Brown-tail, Bucculatrix bechsteinella, Bucculatrix pomifoliella, Coleophora cerasivorella, Coleophora malivorella, Green Pug and Winter Moth. Four other species previously included in the genus Cydonia are now treated in separate genera. These are the Chinese Quince Pseudocydonia sinensis, a native of China, and the three flowering quinces of eastern Asia in the genus Chaenomeles. Another unrelated fruit, the Bael, is sometimes called the "Bengal Quince".
