The Quince  or 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 deciduoustree, growing 5-8 m tall and 4-6 m wide, related to apples and pears, and like them has a pomefruit, 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, most of which rubs off before maturity in late autumn when the fruit changes colour to yellow with hard, strongly-perfumed flesh. 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.
