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, also called medlar, has been cultivated since Roman times, is usually available in winter and eaten when bletted. It may be eaten raw and in a range of cooked 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.
