Pseudocydonia sinensis

Pseudocydonia sinensis or Chinese quince (Chinese: 木瓜; pinyin: mùguā) is a deciduous or semi-evergreen tree in the family Rosaceae, native to southern and eastern China. It is the sole species in the genus Pseudocydonia. Its hard, astringent fruit is used in traditional Chinese medicine and as a food in East Asia. Trees are generally 10–18 metres (33–59 ft) tall.
