Mespilus

Within the subfamily Amygdaloideae, Mespilus is most closely related to Crataegus, Amelanchier, Peraphyllum, and Malacomeles.^[3]

Many authors group Mespilus together with Crataegus in a single genus. When thus combined, the correct species name is Crataegus germanica (L.) Kuntze.^{[4][5][6][7][8][9]}

The common name “snowy mespilus” attaches to certain species of Amelanchier, notably Amelanchier × lamarckii and Amelanchier ovalis.

The genus Eriobotrya was once considered to be closely related to Mespilus. The loquat, one of several Eriobotrya species, was formerly thought to be closely related to the genus Mespilus, and is still sometimes known in some European countries as a medlar and is still sometimes called the "Japanese medlar".

Mespilus germanica features an unusual apple-like fruit. In southern Europe, the medlar fruit ripen fully and can be eaten off the tree, but in northern climates, they require bletting to eat.^[10] This process involves ripening fruit off the tree, usually in a bowl, until soft. Each fruit contains a half dozen or so hard, irregularly shaped seeds that require stratification to germinate. Many cultivars exist, and they are increasingly popular selections carried by perennial and edible landscaping nurseries in North America.
