Mespilus germanica
Mespilus germanica, known as the medlar or common medlar, is a large shrub or small tree in the rose family Rosaceae. The fruit of this tree is also called the medlar. The fruit has been cultivated since Roman times, and is unusual in being available in winter, and in being eaten when bletted. It is eaten raw and in a range of dishes. When the genus "Mespilus" is included in the genus "Crataegus", the correct name for this species is Crataegus germanica (Kuntze). In the southwest of England it historically had a number of vulgar nicknames, such as open-arse and monkey's bottom, due to the appearance of its large calyx.
