Chaenomeles

About

Chaenomeles is a genus of four species of deciduous spiny shrubs, usually 1–3 m tall, in the family Rosaceae. They are native to Eastern Asia. These plants are related to the quince and the Chinese quince, differing in the serrated leaves that lack fuzz, and in the flowers, borne in clusters, having deciduous sepals and styles that are connate at the base.
