The Shipova (× Sorbopyrus auricularis) is a hybrid of the European Pear (Pyrus communis) and the Common Whitebeam (Sorbus aria). It is a small to medium-sized tree growing to 10-18 m tall, with deciduous oval leaves 7-11 cm long and 5-6 cm broad. The fruit is a pome 2.5-3 cm long; it is edible with a sweet, yellowish flesh, which tastes similar to a Nashi Pear.

History

The hybrid, known as the Bollwiller Pear, first arose at Bollwiller in Alsace, France, before 1619, and has mostly been propagated by grafting since then; it is nearly sterile, only rarely producing any viable seeds. Two successful seedling propagations have been named as the cultivar 'Bulbiformis' and as the species Pyrus malifolia. However shipova trees are not widely cultivated. Shipova is the only known species in the nothogenus × Sorbopyrus (the hybrid genus of Sorbus and Pyrus)

Alternative genus names

The genus Sorbopyrus (a name published in 1906) has also been known as Bollwilleria Zabel (published 1907), and as Pyraria A.Chev. (published 1925).^[3]
